Introduction
A new feature-version of FlexSim Simulation Software is released several times per year. In order for client PCs to be able to run a licensed version of the upgraded software, you may need to upgrade the activated license(s) on your license server.
Licenses with a current maintenance subscription are eligible to be upgraded to the latest version.
If you don't understand how licensing works for different FlexSim versions, please review our Answers article FlexSim Version Numbering.
Overview
There are 6 main steps to upgrading the licenses hosted on your lmadmin or lmtools license server:
- Check if you need to upgrade your license server files
- Return the licenses you intend to upgrade
- Upgrade your licenses
- Activate the upgraded license
- Reread the license
- Upgrade client PCs
Several of these steps have their own fully documented procedures. We'll link you to those resources below.
1. Check if you need to upgrade your license server files
If your organization's license server was installed previously and hosting licenses for FlexSim 25.1 or lower, it may need to be upgraded for compatibility with FlexSim 25.2 and higher. Click here to learn more or go directly to the latest license server files.
After you have upgraded your license server files, move on with the rest of the upgrade process, as outlined below.
2. Return the licenses you intend to upgrade
The steps to return a license-server-based license are fully documented. Choose the link below that best matches your needs, depending on whether your license server can connect to the Internet:
Be sure to return ALL licenses you wish to upgrade.
3. Upgrade your licenses
NOTE: Licenses with expired maintenance will not upgrade. Timed licenses do not upgrade. Only permanent (not timed) licenses under current maintenance can be upgraded. Contact your salesperson for extending a subscription or other circumstances.
Log in to your FlexSim Account.
If you were already logged in to your FlexSim Account, in the top navigation menu hover over your initials icon and choose Reload Account.
Now in the top navigation menu, choose Licenses > List.
Check that the available seat count is equal to the total. All of a license’s seats should be returned for it to upgrade.
Click on the Upgrade Licenses button.
If you have several licenses to upgrade and all are owned by or shared with your FlexSim Account, they will all be upgraded at once. Please be patient while the upgrade process works in the background.
When the page refreshes, eligible licenses will have a new activation ID for the latest version of the software. Your license code indicates its version at the end of the code to help you know what versions your license will properly activate. Review license code format.
4. Activate the upgraded licenses
The steps to activate a license-server-based license are fully documented. Choose the link below that best matches your needs, depending on whether your license server can connect to the Internet:
5. Reread the license
Your license server needs to start serving up your newly activated licenses. You can either restart your license manager service, or use your license manager's option to reread your licenses.
The steps to reread your licenses differ depending on which license manager you are using to host your licenses. Use these links to jump to instructions for the license manager you're using:
6. Upgrade client PCs
Finally, upgrade your PC with a version of FlexSim appropriate for your new license (learn how licenses work across versions).
After installing a new version of FlexSim, you will need to configure it to get a license from your license server. There are two ways a client PC can be configured. Choose the method below that most closely matches the main use case for your client PC:
- Single-user client PCs - this method configures settings that are saved on a per-user basis.
- Multi-user client PCs - usually appropriate for a university computer lab or other shared-PC situation, where the configuration should be computer-based.
