Problem Description

The error message that can appear if 3.5 users are trying to check out a license from a COMSOL 3.4 license manager is

Error: License server system does not support this version...

I need to update the license manager. Which is the recommended method to update both the COMSOL License Manager and the COMSOL applications from 3.4 to 3.5?

Solution

Start by updating the license server, then upgrade the COMSOL application on the client computers.

Please note that the COMSOL 3.5 license manager binaries and license file (license.dat) are backward compatible with COMSOL 3.4 program installations. This means that any COMSOL 3.4 user on a floating network license can continue to work, also with the updated license manager.

Upgrading the COMSOL License Manager on Linux/Sun/Macintosh

1. Install the COMSOL 3.5 License Manager on the license server. Please see the section License Manager Installation in the COMSOL Installation and Operations Guide for instructions.
2. Now stop the COMSOL 3.4 license manager: Make the comsol34/license/$arch directory the current directory, where $arch is either glnx86 (32-bit Linux), glnxa64 (64-bit Linux), glnxi64 (Itanium Linux), sol2 (32-bit Sun), sol64 (64-bit Sun), macosx (PowerPC Mac), maci32 (32-bit Intel Mac) or maci64 (64-bit Intel Mac). Stop the COMSOL 3.4 license manager with the lmdown command:
   
   ./lmdown -c ../license.dat


3. Make the comsol35/license/$arch directory the current directory.
4. Start the COMSOL 3.5 License Manager manually with the command:
   
   ./lmgrd -c ../license.dat -L /var/tmp/comsol35.log
   
   
5. Update the boot script that starts the COMSOL License Manager. Depending on platform, the default boot script location is:
   
   

   SuSE Linux	/etc/init.d/comsol34lm
   Debian Linux	/etc/init.d/lm_comsol
   Linux	/etc/rc.d/rc.local
   Sun	/etc/init.d/lmgrd
   Macintosh	/Library/StartupItems/COMSOL_Lmgr/COMSOL_Lmgr

   
   Open the file in a text editor and set the FP path variable to the COMSOL 3.5 root directory. Please note that you need to be superuser (root) to edit boot scripts.

The update is now complete. The license server does not need to be restarted.

Upgrading the COMSOL License Manager on Windows

The COMSOL 3.5 License Manager is usually installed as a Windows service. Use the LMTOOLS license utility program to upgrade the service to use the COMSOL 3.5 license manager binaries and license file.

1. Install the COMSOL 3.5 License Manager on the license server. Please see the section License Manager Installation in the COMSOL Installation and Operations Guide for instructions.
2. Start the LMTOOLS license tool from the Start menu>Programs>COMSOL 3.5>License Tools>LMTOOLS.
3. On the Service/License File tab, select the COMSOL License Manager.
4. Go to the Start/Stop/Reread page and click the Stop Server button.
5. Go to the Config Services page. Change the paths to lmgrd.exe, license.dat, and the debug log file comsol35.log so that they all point to the COMSOL 3.5 installation. Click the Save Service button.
6. Go to the Start/Stop/Reread page and click the Start Server button.
7. Choose Exit from the File menu to close LMTOOLS.

The update is now complete. The license server does not need to be restarted.
