Hello Altair Support Team,
I am using the free Altair Student Edition license for Simcenter PSIM 2026.1.
My situation:
- I am using the same physical computer as before.
- I previously activated my Student Edition license on this computer.
- I recently reinstalled Windows on the same computer.
- After reinstalling Windows, I tried to activate my license again using Altair License Utility, but the activation failed.
Error message:
This license was already activated using different HostIDs.
Before this activation error, PSIM also displayed the following licensing errors:
- Error Code 15: Unable to connect to license server at
6200@localhost. - Error Code -29: Requested CT/TTF license not found for given customer ID.
My Student Edition license is still within its validity period. However, I can no longer deactivate the previous activation because the original Windows installation and its local license configuration are no longer available.
Could you please check my license activation record and reset the previous HostID binding, or advise me on how to reactivate my Student Edition license on this same computer?
I would like to continue using PSIM 2026.1 with my existing Student Edition license.
I can provide my current HostID and any additional diagnostic information privately if needed.
Thank you for your time and assistance.
Best regards
