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.  

Assumed configurations   All steps below assume that you followed the installation instructions as described in our license server installation instructions, and that all FlexSim's license server files were extracted to the location C:\FlexSim_LMTOOLS. Throughout these instructions we will reference files inside that folder.   Reread the license   Within your FlexSim_LMTOOLS folder, right-click lmtools.exe and choose Run as administrator. You may need to accept a permissions prompt. Go to the Start/Stop/Reread tab. Choose the FlexNet License service for your FlexSim licenses. The name of the service could be FlexSim_License, but the service could have been given a different name. Press the ReRead License File button. Close lmtools.

Remembering the proper credentials To log in to lmadmin's Administration area you need know the port number your license server manager is hosting on and your lmadmin admin password. lmadmin's default port number for serving its web-based user interface is 8090. There is a very good chance that your system is hosting lmadmin on its default port. On your license server, open a browser and go to http://127.0.0.1:8090 to see if this will open lmadmin's web-based interface. The default login information for lmadmin's Adminstration area is username admin and password admin. Upon your first logging in to the Administration area you would have been prompted to create your own new password consisting of at least 8 characters. If you have forgotten either the port number or your admin password, there is unfortunately no way to recover these. You will need to uninstall, then reinstall lmadmin. If you do not wish to do so at this time, you should be able to start serving your upgraded FlexSim licenses by restarting the lmadmin64 Windows service. Logging in to lmadmin Use a web browser to connect to the lmadmin service at https://127.0.0.1:8090 (specify a different custom port besides 8090, as necessary). The FLEXnet Publisher interface should open. Click on Administration to sign in. After logging in to the Administration portal, click the Vendor Daemon Configuration tab on the bottom left. Click on the flexsim daemon. Reread the license If there is a Start button, that means that your flexsim vendor daemon is currently stopped. Press the Start button to start the vendor daemon using your upgraded licenses. If there is a Reread License Files button, that means that your flexsim vendor daemon is currently running, and serving the old licenses. Press the Reread License Files to start serving your newly activated and upgraded licenses.

FlexSim licenses can either be standalone or network-based. Each license model has its pros and cons. Learn more about these two different license models. You're here because you've chosen network licensing and you're ready to get started. A license manager by any other name FlexSim is licensed using technology from Revenera's FlexNet. FlexNet is one of the top software licensing technologies and is used by many large software companies, including several others in the engineering software space. FlexNet offers two different license managers: lmtools and lmadmin. You decide which platform will work best for your organization's needs. (Spoiler alert: we like lmtools best). lmtools Hosting your FlexSim licenses with lmtools lmtools is a simple utility for creating and managing the licensing service that will serve your FlexSim licenses to your organization's client PCs. This basic utility isn't installed - it is a simple executable. It has no 3rd party dependencies. For maximum security, compatibility, and simplicity, FlexSim recommends using lmtools. Many organizations that add FlexSim to their toolkit already use lmtools for managing their license hosting services for other software, so using lmtools to manage your FlexSim licenses just makes sense. Even if your FlexSim purchase marks the first time your org has set up a license manager, lmtools is a great way to go, and is our recommended license manager. Visit Hosting your FlexSim licenses with lmtools for a complete reference on configuring your license server using lmtools. lmadmin Hosting your FlexSim licenses with lmadmin lmadmin is FlexNet's newer, shinier license manager. It includes a web-based front end, so all the administration is done from your web browser. It is more complex than lmtools, serving both the licensing service and a management front end, and lmadmin relies on Java, which you will need keep up to date with patches and security updates. FlexSim usually does not recommend lmadmin, mainly because of the more complex configuration needed to host and manage the web front end (including additional firewall considerations, an extra username and password, etc.), its reliance on Java, and the fact that many FlexSim users already host other software licenses using lmtools.
