All,

We recently purchased a Motor-CAD license (via the Ansys Academic Research Electronics Suite) and applied it to our license server. We have a user that can check out a Motor-CAD license, but after 2 minutes or so, he seems to lose access to it.

The error message on the client is:

ANSYS LICENSE MANAGER ERROR

Cannot connect to the license server system. The license server manager (lmgrd) has not been started yet, the wrong port@host or license file is being used, or the port or hostname in the license file has changed.

Unable to obtain license: motorcad

Unable to check out feature: motorcad

In the license server log, I see his license denials and "v2025.0506"(License server system does not support this version of this feature. (-25,334:104 "Connection reset by peer"))^^^ 2025.0506 firstname.lastname ipaddress 26988 0 0 5 0:0:0 N/A 11 19 1-10-2025 14:30:46 NO ^^^. If this is the issue, how do we determine what version of this feature is supported? Our license server is 2025 R2. On the client, he has installed the Motor-CAD update package from the Ansys client portal (version 2025_R2). Any help on this would be appreciated.

Hello Rachael, 

Can you please confirm if ansys license file and license manager version is greater than or equal to motorcade version?

Wishes, 

Mrunali.

Mrunali, thanks for the message. Yes, all versions matched. I was able to figure it out and am posting the solution in case someone runs into the same issue. I was not aware that we had to license Motor-CAD separately, I thought it shared the license server set within the 2025 R2 licensing settings. Here was the fix: Open Motor-CAD - License - Configuration. Used Ansys as the License System - license checkout (at startup - default) - check all requested licenses for Motor-CAD - then leave the license ini file path default and put in our port@licenseserver in the blank field. Update and close. I verified in the LM logs that there were no additional denials - feature was being checked out as it should be. 

We ran into an additional issue with the ansyslmd.ini file on a desktop where we wanted to install and license Motor-CAD, it was complaining about being unable to update the ansyslmd.ini file. Right-clicked the .ini file, checked security settings, updated so it had "write" permissions, saved and closed. That resolved it.
