Have you ever encountered this error?   --- Status... Status: 4 Creating request Status: 5 Request created Status: 6 Context created Status: 7 Connected to remote server Status: 0 Error ERROR: flxActAppReturnSend - (50018,41145,32) "Failure to send request or receive a response for an unspecified reason. Recovery: check parameters used for the request." ---   We're looking for more information on this error. If you're encountering this error, please comment below.   This error appears to be a communication error where the client PC may have an Internet connection, but is not successful in contacting the license server. This may be due to a firewall misconfiguration or a proxy server.   You may want to make sure your client PC can connect to FlexSim's servers (addresses and ports listed in this article).   You may also need to configure FlexSim to communicate through your proxy server:  

Background   The method for licensing a single-user client PC saves client PC license settings to the Windows profile data of the signed in user, so license settings are saved on a per-user basis.   In cases where the exact number or identity of PC users is not predetermined, such as in a university computer lab, it is impractical to license users individually in this manner. Another use-case for this method is when FlexSim Software is automatically pushed or deployed to client PCs. Having the licensing as part of the deployment is useful.   For this mult-user method we'll use a license file on the client PC to license FlexSim software generally for any user of the PC.   Use a license file   Create a plaintext license file   On the client PC create a plaintext license file named flexsim.lic with the following 2 lines (exclude any line numbers):   SERVER 127.0.0.1 ANY 26914 USE_SERVER   If your Windows settings do not show file extensions, it is possible that your flexsim.lic license file is actually named flexsim.lic.txt, which will not work. Be sure to show file extensions and make sure your license file ends with the .lic file extension. The actual name of the file is not important (it could be helloWorld.lic, for instance), but it needs to end in .lic.   Modify   On the client PC, modify your new license file with the following changes:   On line 1 change "127.0.0.1" to the IP address or fully qualified domain name of your license server. If you modified your license server with custom port numbers, on line 1 replace the default port 26914 with your custom port number.   Install   With FlexSim software installed on a client PC, your new license file should be copied into FlexSim’s installation directory in the following location:   C:\Program Files\FlexSim <version>\program\   Your exact folder path could differ based on custom installation locations or FlexSim version, but it should be placed into FlexSim’s program\ folder.   Multiple license servers?   If your FlexSim licenses/seats are spread across multiple license servers, you can configure your client software to try to pull a license from any of your multiple license servers. Simply create a new license file for each possible license server and save each to the same program\ folder. In this scenario, in your program\ folder you would have multiple license files listed, like this:   flexsim1.lic flexsim2.lic flexsim3.lic etc. Each license file should reference a different license server and its port number.   Next   Check out the next article to learn how to verify that your client PC is licensed, and what to do if it isn't: License Server - Verify client PC licensing.  

Sometimes things don't work out the way you thought they would. Usually, at least with license servers, it just means that you missed a step, or there is some issue that wasn't considered. Below we'll outline some things you should check:   Server configuration   - Check the service   Is the FlexSim_License service you created using LMTOOLS up and running? When you created and configured your licensing service, did you check the log file? Look for any errors or issues in the log. Troubleshoot the service if necessary.   - Local test   You can rule out configuration issues by installing FlexSim locally on your license server. Configure the local FlexSim installation using the port you specified (default is 26914) and the local IP address 127.0.0.1, to point your local FlexSim installation to the local license server to see if your license server can license itself.   - Connectivity problems   If your local test works, then your client PC licensing issues may actually stem from connectivity problems. In that case, check out our article Client/Server connectivity.   - Check, check again   Double check that your server is configured properly. When viewing your license service’s log file, you should see indications of ports in use, features being served, etc. (lmtools, lmadmin). If no features are listed, or port numbers are different than what was expected, please revisit the configuration guide (lmtools, lmadmin). Carefully read and execute each step of the instructions to make sure that you have properly configured your license server.   Overzealous anti-virus   Some anti-virus solutions prevent unrecognized services from running or accessing necessary functionality. If a local test (above) works, you may only need to test disabling anti-virus solutions on the client PC. Or if you're trying to get the license service to run on the server, you may need to test there also. Remember to reactivate your anti-virus software after this experiment.   Version or product mismatch   Your actual license, activated to your server using flexsimserveractutil.exe (online, manual), must be for a FlexSim version the same or greater than the software’s version number.   Your license is also for a specific product (FlexSim vs FlexSim Healthcare vs FlexTerm, etc.).   See the article FlexSim Version Numbering, for more information regarding FlexSim versioning and how it relates to licensing.   Seats all in use   If your FlexSim client software is not obtaining a license from the server, it’s possible that all seats are already in use on other client PCs. Check the log files (lmtools, lmadmin) to determine where your seats are currently in use.

You've installed, configured, and started your license server. FlexSim is installed and your client PCs are set to get a license from your license server. How can you tell if they're communicating and licensing properly? You can check both the client PC and the license server to make sure that licensing is happening: Client PC Within FlexSim software on the client PC, go to the main menu, Help > About FlexSim. The popup should indicate the activated license type. Test licensed features to see if they work. Check the article FlexSim Feature Limitations by License Type to see what features should be available given your license type (Enterprise, Educational, Student, Runtime). For instance, the Experimenter feature should be available to each of those license types. License Server In lmtools logs (Config Services > View Log…), you should see that a seat is in use. (See How do I read/analyze my vendor daemon logs? What do the various lines mean?). In lmadmin logs you should see that a seat is in use. If your client PC is not getting licensed and/or your license server logs don't indicate communication with a client PC, check the license server troubleshooting steps.

Background   Often a client PC is used by a single user who should have access to change license settings.   This method saves licensing settings to the user’s Windows profile. In this manner licensing is saved on a per-user basis and should be completed in advance for each FlexSim user on this client PC.   In some situations it is better to license the PC once for any user who might log in. This can be the case for a university computer lab, for instance. If your situation would be better served by licensing the software one time for all users of the PC, please check out our guide to license a mult-user client PC.   Configure Licensing   To license an individual Windows user, do the following while logged into Windows as that user:   Open FlexSim software on the client PC by right clicking the program icon and choosing Run as Administrator. You won't normally need to start FlexSim under elevated privileges, but sometimes licensing the PC for the first time requires it. Go to the software’s main menu and select Help > License Activation. Navigate to the License Server tab. Check Use concurrent licensing. Enter the License Server Address using the form port@host, where host is an IP address or fully qualified domain name (FQDN). For example, if your license server is reachable via the FQDN licenseserver.mycompany.com: If you used FlexSim’s default license service port number, enter 26914@licenseserver.mycompany.com. If you specified a custom port, use that number instead. For example, if you entered 27500 as your custom port number, you should enter 27500@licenseserver.mycompany.com. Click Apply Configuration.   Multiple license servers?   If your FlexSim licenses/seats are spread across multiple license servers, you can configure your client software to try to pull a license from any of your multiple license servers. Simply enter all available license server options, separated using a semi-colon, like this:   26914@lic.server.one;27001@lic.server.two;27009@lic.server.three   Here is an example image:   The software will attempt to contact each license server in turn until it obtains a seat or has attempted all license servers and failed.   In the example above, lic.server.one and lic.server.two are fully qualified domain names to properly configured license servers, with lmgrd serving on ports 26914 and 27001 respectively. You could also use an IP address instead of a FQDN.   Next   Check out the next article to learn how to verify that your client PC is licensed, and what to do if it isn't: License Server - Verify client PC licensing.

You should have already completed all preceding steps found in the article Hosting your FlexSim licenses with lmtools, including all those under the headings "Preparation and Prerequisites" and "Activate licenses to your license server". Your license server will communicate with client PCs using two executables, the lmgrd.exe licensing service and the flexsim.exe vendor daemon.   This article shows how to add exceptions for these applications through Windows Firewall. If you have additional firewalls or network appliances that need to be configured, please check the section Port Considerations at the end of this article.   Allow an app through Windows Firewall Port Considerations   Allow an app through Windows Firewall   Windows Firewall allows you to specify certain applications that will be allowed through different network types. If you're not sure about firewalls and networking, be sure to contact someone in your organization that administers these things.   You will need administrator privileges on your license server to add firewall exceptions.   Open the Allowed apps interface   Click the Start button or press the Windows key, then type Firewall into the search box. Choose the option to Allow an app through Windows Firewall.     If you don't see that option, you can choose the option Windows Defender Firewall at the top of the search results. This will open the Windows Defender Firewall topic the Control Panel. There you can choose Allow an app or feature through Windows Defender Firewall in the side panel:     Add a firewall exception for lmgrd.exe   In the Allowed apps window, click the Change Settings button, then the Allow another app… button.     In the Add an app window that opens, click the Browse… button. Navigate to extracted license server downloads. Double click lmgrd.exe to choose the file.     Click the Network types… button.   Check the boxes for the various network types that the firewall should allow. We recommend allowing your FlexNet licensing to communicate across all network types, but contact your server or network administrators if you're not sure.     Click Okay to close the Choose Network Types window.   Back on the Add an app window, click the Add button.   Add a firewall exception for flexsim.exe   Repeat the steps above for flexsim.exe:   Click the Allow another app… button. Browse… to your extracted license server downloads. Select flexsim.exe. Click Network types… and choose the appropriate networks to allow access to lmgrd.exe. These should be set to the same settings chosen for lmgrd.exe, and you can usually allow all network types - domain, private, and public. Click the Add button. Click OK to close the Control Panel window.   Port considerations   You may need to allow communication through other firewalls or network appliances, depending on your network topology and specific licensing plans for how and from where client PCs will connect to the license server. Usually for such firewalls or devices you will configure inbound and outbound port exceptions to allow your license server communications to pass through.   A FlexSim license server has its ports defined in a flexsim.lic license file, specified when you configured your FlexSim_Licensing service.   Our default ports are as follows:   lmgrd.exe - licensing service - port 26914 - TCP flexsim.exe - vendor daemon - port 56914 - TCP   There is a chance you specified custom your port numbers. If you're not sure you can check your flexsim.lic license file. Read more about FlexSim's license file and default vs custom port numbers in our article FlexSim's license file.

A license file? What's that? License not included Default port numbers Custom port numbers Automatic port numbers Resolving port conflicts A license file? What's that?   When you set up a license server to host your FlexSim licenses, you'll configure settings for a FlexNet licensing service (lmtools, lmadmin). Some settings are specified in a plain text file ending in the .lic file extension.   You'll find FlexSim's license file, flexsim.lic, alongside the other downloaded license server materials (lmtools, lmadmin). The license file is just plain text. You can open it and examine its contents using your favorite text editor (Notepad, Notepad++, VSCode, etc.).   If you've used FlexNet licensing before, you know that often a .lic license file contains license codes and hashes that authenticate a product license on a computer system. However, this isn't the case for FlexSim.   License not included   FlexSim's license file doesn't contain any license information. Instead FlexSim licenses are held in FlexNet's Trusted Storage. That's why every customer downloads an identical license file alongside all our other license server materials.   FlexSim's flexsim.lic license file is a bootstrapper that tells FlexNet's licensing service to find FlexSim's license information in Trusted Storage, and to specify port numbers that will be used for serving the licenses.   Here are the complete contents of FlexSim's default flexsim.lic license file:   SERVER this_host ANY 26914 VENDOR flexsim port=56914 USE_SERVER FEATURE serverfeature flexsim 1.000 permanent uncounted HOSTID=ANY \ SIGN="05CB 6F61 116D 06E3 A08D CAFB FC5C BEF3 DF53 BDC6 AF68 \ 060C 27B8 9968 CB94 0515 2BE7 E30C 2FAF C0D6 1D77 CCEB 878E \ 2D67 1434 0E3F 6BA5 1FDA BD35 F98D"   Default port numbers   You can see on lines 1 and 2 above where we've defined FlexSim's default license server port numbers:   26914 (lmgrd.exe - the licensing service. Client PCs specify this port on the license server.) 56914 (flexsim.exe - the vendor daemon)   Custom port numbers   While we recommend using FlexSim's default port numbers, you can edit your flexsim.lic file to specify your own custom port numbers. Simply replace the default port numbers in your plain text license file with any valid, available port numbers you wish to use.   Automatic port numbers   Also not recommended - you can also remove the port numbers (and the “port=”) from the flexsim.lic file to allow the FlexNet Licensing Service to auto-assign port numbers, like this:   SERVER this_host ANY VENDOR flexsim USE_SERVER FEATURE serverfeature flexsim 1.000 permanent uncounted HOSTID=ANY \ SIGN="05CB 6F61 116D 06E3 A08D CAFB FC5C BEF3 DF53 BDC6 AF68 \ 060C 27B8 9968 CB94 0515 2BE7 E30C 2FAF C0D6 1D77 CCEB 878E \ 2D67 1434 0E3F 6BA5 1FDA BD35 F98D"   We don't recommend auto-assigned port numbers since the FlexNet Licensing Service could auto-assign new, different port numbers any time the licensing service is restarted (such as when your server restarts to install Windows updates, etc.).   Port numbers that change regularly can make it more difficult to maintain the firewall exceptions or other network settings needed for your license server to communicate properly with client PCs.   Resolving port conflicts   If your licensing service has trouble starting or properly hosting licenses, or if other licensing services fail after starting your FlexSim licensing service, you could have a port conflict.   You could try specifying your own custom ports as described above. This is a good solution if you know what port numbers are in use with existing services and can choose unused port numbers. After changing the port numbers defined in your flexsim.lic license file, restart your FlexSim_Licensing service.   If you’re not sure what port numbers to try, you could allow FlexNet to auto-assign port numbers itself – it tries to find and use free ports, though it isn’t foolproof. After modifying your flexsim.lic license file to allow automatically chosen port numbers, restart your FlexSim_License service. Then check the log file (lmtools, lmadmin) to see what ports were auto assigned.   If everything works, we suggest that you take the port numbers automatically assigned by FlexNet and hardcode them into your license file. This way you can maintain static exceptions more easily in your firewall. Be sure to configure your client PCs to use the new license service port number.  

You should have already completed all preceding steps found in the article Hosting your FlexSim licenses with lmtools, including all those under the headings "Preparation and Prerequisites" and "Activate licenses to your license server". At this point you're ready to install, configure, and start the service that will serve your FlexSim licenses.   Create the service Configure service permissions Start the service Check the service status Troubleshooting problems with the service   Create the service   We'll use lmtools to create your new licensing service.   On your license server, in your extracted download folder of FlexSim license server materials, right-click lmtools.exe and choose Run as administrator. Go to the Config Services tab. Create a new licensing service by typing FlexSim_License into the Service Name input field. The Service Name field looks like a dropdown selector, but you can click in it to type a new name. Use the 3 Browse buttons to specify the paths to files (lmgrd.exe, flexsim.lic, log.log) that are also included with the FlexSim license server materials. Check the boxes for Use Services and Start Server at Power Up. Press the Save Service button in the upper right. Confirm the save by choosing Yes. You may receive an error message regarding "Windows preferred path". This is normal and this message can be safely ignored.   Configure service permissions   Your new FlexSim_License service needs permissions set to function properly.   Click the Windows Start button or press the Windows key, then type “Services” into the search box in the Start menu, and press Enter. Windows will search for and open Windows Services Manager. Find FlexSim_License in the list of services. If it is missing from the list, see the section Troubleshooting the licensing service below. Open the FlexSim_License service’s Properties window by double-clicking its name. Go to the Log On tab. Choose the option to Log on as: Local System account. Press OK to close the FlexSim_License Properties window.   Start the service   While still in Windows Services Manager, use the Start link to start your new FlexSim_License service.     You should see a status bar showing the startup progress. The service usually starts in under a minute.   If there are any errors or other problems with starting the service, skip to the section Troubleshooting problems with the service.   Check the service status   After the service is started, head back to lmtools to check the log. You can view the service log from the Config Services tab, press the View Log... button, located toward the lower right of the Config Services panel.   You should find the following information in your log file:     lmgrd.exe is listening on port 26914. This is the port the licensing service will use when listening for client PC communication. The bootstrap license file flexsim.lic was found and loaded. (This is not a license file specific to you and does not contain your license info. FlexSim licenses use Trusted Storage and licenses are activated to your license server using flexsimserveractutil.exe). The flexsim.opt Options file was found and loaded. A list of product features activated in your server's Trusted Storage. Your feature set may differ somewhat from this example, depending on your license and product, but you should see several of the features above. 900 seconds is the minimum timeout allowed by FlexNet, and we configure our installation to use this minimum value using the options file. The flexsim.exe vendor daemon is using port 56914.   To close the log, press the Close Log button, toward the lower right of the Config Services panel in lmtools.   Troubleshooting problems with the service   Did everything work? If not, perhaps you have one of these issues:   The FlexSim_License service is not listed as an installed service in Windows’ services. The FlexSim_License service does not start manually. The FlexSim_License service does not start up automatically when the computer restarts.   If any of these apply to you, please check the following:   You ran lmtools as a user with admin rights, and right clicked the program to choose Run as Administrator. On the Config Services tab, you checked the boxes Use Services and Start Server at Power Up. There isn’t already a process running or service installed named FlexSim_License. lmgrd.exe, flexsim.exe, and all other files downloaded together with them are in the same folder, and in a file path that does not contain any folder named “FlexSim” (case insensitive). The FlexSim_License service must run as an account with proper permissions. It’s possible that the Local System Account setting specified in Configure service permissions above does not have adequate permissions, and you will need to specify the service to run under a different account. Work with your server administrator or IT department to determine an account with the proper permissions to run your license service. You could have a port conflict, where one or both of the ports specified in your flexsim.lic license file are in use by another service on your license server. Check the section Resolving port conflicts. Some anti-virus solutions prevent unrecognized services from running or accessing necessary functionality. If your license service won't start, try temporarily disabling any anti-virus solution installed on your license server. If this fixes the issue, work with your IT administrator to modify your anti-virus settings. Remember to reactivate your anti-virus software after this experiment.  

First things first Sometimes the easiest method for fixing a standalone license is to simply activate the same license again. No need to return first. Just get the full activation ID for any broken licenses and activate them again. Look for the broken licenses within FlexSim by going to Help > License Activation > View Licenses tab and pressing the View Licenses button. Scan the license information for licenses that indicate they are **BROKEN**. For licenses that are broken, look up the full activation IDs in your online FlexSim Account. Using the full activation IDs for each broken license, activate the licenses normally within FlexSim by going to the Activate tab and pasting and activating each activation ID in turn. No need to return the licenses first. In case you need more detailed activation instructions, see: Standalone - Activation - Online Standalone - Activation - XML / Offline If you completed the 3 steps above but encountered error messages, it is time to manually repair your licenses. Okay, time to repair Standalone licensing does not have a method for repairing online. Here are the steps to manually repair your license. These instructions apply to FlexSim 2016 and later. If you are using an older version of FlexSim, please download FlexSim's latest version and follow these instructions. You can manage your older FlexSim licenses from the latest software - the License Activation window will still show your older licenses and you'll be able to complete all these steps for your broken pre-version-16.0 licenses. Open FlexSim as an administrator by right clicking the program icon and selecting Run as Administrator. From the main menu, go to Help > License Activation. Go to the Advanced tab, then the Repair tab. For each broken license listed in the License selector box, click the Generate XML Request button. Save each XML file to a convenient location on your computer. Log in to your FlexSim Account. From the top navigation header click the Licenses link, then choose Manual XML in the Licenses submenu. Upload your XML files by dragging them onto the drop zone. Your uploaded XML requests will be processed. Upon completion, you will be prompted to download each XML response. In FlexSim (your instance opened above in step 1 using Run as administrator), you should still be on the same License Activation > Advanced > Repair tab. Process each response by pressing the Process Response button and browsing to an XML response. FlexSim should successfully repair the license. After repair it should be usable and returnable.

These instructions are to be performed on a license server hosting FlexSim licenses. You will need the license server files. If you do not already have a copy of those linked files on your license server, download them to your license server then extract the entire archive to a convenient location. Run flexsimserveractutil.exe as an adminstrator by right-clicking the .exe and selecting Run as Administrator. Go to the main menu, Tools > View License Rights. Scroll through the displayed license information. Find any activated licenses that indicate they are broken. Find each broken license's Fulfillment ID (starts with FID_). Copy the Fulfillment ID to the clipboard (highlight including the FID_ prefix, through to the end of the line. Ctrl-C to copy). Go to the main menu. Select Tools > Manual Activation > Generate Request. Select the Repair option. Paste the Fulfillment ID into the field (Ctrl-V). Delete any spaces that may have been included before or after the pasted Fulfillment ID. Browse to a location where you will save the XML repair request. Choose a file name for the saved file. Press the Generate button. Repeat steps 4-10 for any broken licenses. Transfer the XML repair request files to an Internet connected computer. The files are plain text XML and can be manually examined in any text editor if necessary for security purposes. Be sure not to modify the files, including line endings. If the file is modified in any way, the various hashes in the file will register the change and the request will fail. Log in to your FlexSim Account. Click the Licenses link in the top navigation menu, then choose Manual XML in the Licenses submenu. Upload your XML files by dragging them onto the drop zone. Your uploaded XML requests will be processed. Upon completion, you will be prompted to download each XML response. Transfer the XML response files back to your license server. In flexsimserveractutil.exe (your instance opened above in step 1 using Run as administrator), from the main menu, choose Tools > Manual Activation > Process Response. Process each response by browsing to an XML response, then pressing the Process button. The license should be successfully repaired. After repair it should be usable and returnable.

Have you received this licensing error? Operations error: 7131 Server activation is not allowed to activate entitlement line item: Make sure the license model is a server license model. You may encounter this error if you attempt to activate a standalone license using flexsimserveractutil.exe on a license server. A standalone license is intended to be activated directly within FlexSim Simulation Software installed on a client PC. Please see our instructions for standalone licensing for the procedures to use with your standalone FlexSim licenses.

Have you received this licensing error? Operations error: 7466 The return of the fulfillment is denied by the return policy because max return exceeded. This error indicates that returns are disabled for your license. Your license is configured for one-time activation onto a computer. If you believe your license should be able to transfer from one computer to another, please contact your local distributor to discuss the situation.

Have you received this licensing error?   Operations error: 7288 The activation of the fulfillment is denied by the activation policy because fulfill count exceeded the available seat count.     Here are some common reasons you may encounter this error, along with some possible solutions.   All seats are already in use   Problem: All the seats of this license are already activated. There are no available seats left to activate.   Solution: You must return a seat from a computer where it is currently activated. Once a seat has been successfully returned it is available for a new activation.   If you are not sure where your license is currently activated, there are two main methods for finding out:   Go on a hunt: On each computer where the license may be activated, check the license status by opening FlexSim and going to Help > License Activation > View Licenses tab > press the View Licenses button. This will show you the license information for the current PC. Check the history: You can view your activation/return history from your FlexSim account's licenses page. On the Licenses page, expand the folders until you can see the Activation ID you are trying to track down. Click the Activation ID to load the history for this license. This history includes dates/times of the activations and returns. If the information is available it will also list the computer name where the license was last activated and the Windows username of the logged in user who completed the action. If the computer where your license was activated has been stolen, destroyed, wiped, etc., please contact your local distributor to discuss a solution.   Activation ID is obsolete   Problem: You are trying to activate an obsolete activation ID. An activation ID can become obsolete if it has been cancelled, replaced, or upgraded.   Solution: Make sure to use the most up-to-date version of your license. Log in to your FlexSim account to view your latest license codes.   Consider the following scenario: You purchased a FlexSim license and were emailed a license code. You used that license on your laptop for several years, upgrading FlexSim as new versions were released and following the prompts to upgrade your license as needed. Now you have purchased a new laptop. You successfully returned your license from your previous laptop. On the new PC you installed FlexSim and needed to get it licensed. You looked up your original license code from your years-old email, but when attempting to activate you received error 7288.   The reason is that over the years as you upgraded FlexSim you also upgraded your license code. The old, original license code is obsolete. You must log in to your FlexSim account to get the most recent license code. With the new license code you are able to successfully activate your license on your new laptop.

Protocols, ports, and addresses A license activation or return will attempt to make HTTP (port 80) and HTTPS (port 443) connections, currently with the following servers: license.flexsim.com www.flexsim.com sw.flexsim.com sw1.flexsim.com Make sure these communications are allowed on your network. To make sure you maintain compatibility with any possible future changes to our server configurations, consider configuring your network to allow communication with any *.flexsim.com subdomain. Troubleshooting Any of the following could prevent your FlexSim software from communicating with FlexSim's license servers: Your computer is air-gapped or otherwise blocked from communicating over the Internet. The FlexSim software is not allowed to communicate over the Internet. FlexSim's above-listed addresses are blocked on your network or computer. Your network communicates through a proxy service but you haven't configured the proxy server settings inside FlexSim. FlexSim's license server may be down due to some outage or maintenance. Let's look at solutions for each possibility: 1. No communication / connection issues If your computer is disconnected from the Internet, you will need to connect in order to activate or return a license online. If this is not possible, please use the Manual XML licensing methods listed at the bottom of this article. You may also see this error if you're on a flaky wi-fi connection, or a slow network connection. The communication must be solid enough that it does not time-out, where the client software is able to receive a response in a timely manner. If you are connected to the Internet but on a slow or unreliable connection, you can fall back to the Manual XML licensing methods, or you can retry the online activation multiple times - it may eventually complete successfully after several attempts. 2. FlexSim's communications are blocked If your computer is connected and you can visit other sites, but FlexSim's licensing actions are still blocked, it could be due to an anti-virus solution or other security measure preventing FlexSim's communications. Work with your IT team to disable such measures and test if FlexSim is allowed to communicate. If so, configure your security measures to allow FlexSim to communicate for licensing purposes, or if that is not possible, use the Manual XML licensing methods listed at the bottom of this article. 3. FlexSim's license server is blocked Perhaps one or more of FlexSim's license server addresses (listed above) is blocked on your network. This could be a deliberate blocking of a specific address, or more likely a general block of a wider range of sites or IP addresses. Work with your IT team to determine if this is the case and if the block can be removed. If that is not possible, use the Manual XML licensing methods listed at the bottom of this article. 4. Proxy is not configured If your network settings require that FlexSim communicates through a proxy server, you'll need to configure the software to do so. For FlexSim version 23.0 and higher you'll do this directly in the software. From FlexSim's main menu, navigate to Help > License Activation > Advanced > Proxy Details. Fill in your proxy server information and click the Apply button. If you're using an older version of FlexSim, you can download this attached model. This is an older model file compatible with FlexSim version 5.0 and up. It has a Model Control GUI that is an extension to the License Activation window that includes this extra tab where you can put proxy details. proxy-details-v5.fsm 5. License is already activated but fulfillment is broken The license you're trying to activate may already be activated on your computer, but in a broken or unusable state. Follow the instructions for your license hosting situation to remove the broken fulfillments: Standalone - Delete fulfillment License Server - Delete fulfillment 6. License server offline There are circumstances when FlexSim's main license server can go offline. Most commonly this is due to regular updates or patches being applied. In this case the server will return to normal operation shortly. Please be patient and try again in a few minutes. In cases where longer maintenance is planned you will find a notification at the top of this community indicating the purpose, date/time, and expected duration of such maintenance. This notification will be given as early as possible to help you plan around such downtime. In rare circumstances an outage could be caused by a failure in one or more of the license server's databases, operating system, server hardware, networking, or data center. When such an outage occurs, we will post a notice at the top of this community and work to restore service as quickly as possible. Help! I need support! If none of the above suggestions work for you, please start a new question and include as many details as possible about what you've already tried and what you see happening. Please be aware that if FlexSim's license server is online and other clients are able to activate and return their licenses successfully, that the issue is within your organization's network or on your computer. The proper place to turn to for support will be to your own internal IT teams. The above information, including the protocols, ports, and addresses and the different troubleshooting suggestions should be enough information to solve the issue. Manual XML licensing If you are not able to allow FlexSim to communicate over the Internet, please use our manual XML activation/return methods for offline systems: Standalone - Activation - XML / Offline Standalone - Return - XML / Offline License Server - Activation - XML / Offline License Server - Return - XML / Offline

When you try to activate offline, the following error might appear in the console: ERROR: flxActSvrActivationRespProcess - (50019, 42107, 10246) "Failure to process response for an unspecified reason. This error may be returned when a valid failure response is received, for example when the activation server denies a request. Recovery: check parameters used for the request." License Server Manual XML Activation error example: Standalone Manual XML Activation error example: If you encounter this error, check the response.xml file you are attempting to process. If it includes the text SERVER_CONFIG or CLIENT_CONFIG, but your Trusted Storage is already configured, you may receive this error. With Trusted Storage already successfully configured, you must generate a brand new activation request. Upload the new request to your FlexSim Account for processing. If the license is available you will be able to download the XML response. This response should process and successfully activate your license. Full instructions for performing manual XML licensing for license servers can be found in our license server installation instructions document. ===== Here are some other items to keep in mind with manual XML licensing on your license server: Download the response XML files and transfer them to their license server without modification. Modifying the XML files in any way will "break" them. This includes line endings and other white space. The files include checksums and if the files change they will not work. The destination license server needs to be the same system where the request was generated. The FlexNet Licensing Service 64 needs to be installed, be a high enough version, and be running properly as a Windows service. Checking these items is covered in our license server installation instructions starting on page 6 with 3. FlexNet Licensing Service. flexsimserveractutil.exe may need admin privileges to write to the proper places on the system. Be sure to right-click the application and choose Run as Administrator.

Have you received this licensing error?   An error occurred in the activation request Operations error: 7109 Invalid activation ID:     This error can occur when you are attempting to activate a standalone license online using the Activate tab.   You may encounter this error if you have incorrectly typed your activation ID, left the field blank, or if the system otherwise does not recognize the license code you have entered as a valid activation ID.   Some older versions of FlexSim also were not able to remove spaces or other whitespace from the beginning or end of the activation ID field, so be sure that any spaces or other extraneous characters are removed from both the beginning and ending of the license code text.

A license server hosting FlexNet enabled products like FlexSim relies on a service called FlexNet Licensing Service 64. As of FlexSim version 25.2, FlexSim requires FlexNet Licensing Service 64 version 11.19.8.0 or higher.   Is FlexNet Licensing Service 64 already installed?   There is a chance that you already have a version of FlexNet Licensing Service 64 installed. Let’s check: Click the Start button or press the Windows key, then type “Services” into the search box in the Start menu, and press Enter. Windows will search for and open Windows Services Manager. If the list of services is not already sorted by name, click the Name column heading. Scroll down to services beginning with F. Do you see a FlexNet Licensing Service 64?   If you find that FlexNet Licensing Service 64 is not installed, or if you only have the 32-bit version (missing the ‘64’ in the service name), skip below to the heading Install the FlexNet Licensing Service.   Check the installed version of FlexNet Licensing Service 64   If FlexNet Licensing Service 64 is already installed, we should make sure it is version 11.19.8.0 or higher. If your FlexNet Licensing Service 64 has a lower version number, you will need to remove the older service and upgrade. We’ll get to those steps soon, but first, let’s check what version is installed:   In Windows Services Manager, scroll down to the entry for FlexNet Licensing Service 64. Double click the service name to open its Properties window. In the middle of the General tab, find the Path to executable. Copy the path location from just after the opening double quote (“) until the final backslash (\) before the filename. This is the path. It is probably something like C:\Program Files\Common Files\Macrovision Shared\FlexNet Publisher\. With the path now copied to your clipboard, note the name of the .exe. It is probably FNPLicensingService64.exe. Open a file explorer (Windows Key + E) and paste the path into the Address bar. Hit Enter to navigate to the path. Right click the .exe file that the service's Properties indicated is the service executable. Select Properties to view the .exe file’s properties. Navigate to the Properties window’s Details tab. The Product version should be version 11.19.8.0 or greater. Make sure that the Product name indicates 64-bit.   If you found that you don’t have FlexNet Licensing Service 64 installed, skip below to the heading Install the FlexNet Licensing Service.   If you found that your version number of FlexNet Licensing Service 64 is lower than 11.19.8.0, you will need to upgrade the service.   Upgrade FlexNet Licensing Service 64   To upgrade your FlexNet Licensing Service 64 to version 11.19.8.0, first complete the following: In Windows Services Manager, right click FlexNet Licensing Service 64 and choose Stop. Navigate to the Path to executable shown in the service’s properties. Rename the service’s .exe file by putting an underscore (_) in front of the .exe’s name. Continue with the instructions below under the heading Install FlexNet Licensing Service 64.   Install FlexNet Licensing Service 64   In your extracted download folder of FlexSim license server materials, navigate into the folder flexsimserveractutil. Right-click flexsimserveractutil.exe and select Run as administrator. Select the menu option Tools > Licensing Service > Install anchor service.   You should receive a confirmation that FlexNet Licensing Service 64 is now installed.     For further information on compatibility of various Flexnet licensing components, see Version Compatibility Between Components.  

Download the files Download FlexSim’s latest lmtools-related files here: https://flexs.im/lmtools-download You can browse archived versions of both lmtools and lmadmin here: https://flexs.im/licenseserver-archive Extract the download Once the download is complete, right-click the .zip archive and choose to Extract All… Save to a folder directly on your root drive. Your lmtools download folder Your extracted folder should end up looking something like this: In later instruction steps, any time we refer to the downloaded files, these are the files we're talking about. Note on location Technically you could save your download files in any folder, but we recommend right at the root drive level for convenience. If you choose to save your download folder in an alternate location, please make sure that the directory path doesn't include any folder named "FlexSim". Since Windows files are not case sensitive, this prohibition also applies to variations like "Flexsim" or "flexsim". We have seen instances where some versions of FlexNet licensing encounter errors when the name of the vendor daemon ("flexsim" in our case) is the same as a folder in the path. A folder that includes "FlexSim" as part of a larger name is fine. For example "FlexSim_Licensing" is a fine folder name. Examples of good paths: C:\FlexSim_LMTOOLS C:\licensing\vendors\FlexSim_LMTOOLS\ C:\Program Data\FlexSim_License\ Examples of bad paths (incompatible folder names bolded): C:\flexsim\ C:\licensing\vendors\Flexsim\ C:\Program Data\licensing\FlexSim\files\
