Cannot install PSIM on Windows 11 after formatting OS

LucianoM

I formatted my computer and did not deactivate the license.

In this context, in my formatted computer, when running as administrator the file AltairPSIM2025.1_win64.exe, a bar is prompted and it reaches 100%, but then nothing happens. The following folder is created:

C:\Users\lucia\AppData\Local\Temp\I1757240545

I have a student license.

Hi @LucianoM

Your license key has been deactivated in Altair One, and you can now reactivate your student license using the same key.

Kindly note, The Altair Free Student Edition license is valid for use on only one device, it cannot be shared or activated on multiple machines at the same time AND Deactivation and reactivation feature is only if a computer breaks down or reformatted and is only allowed a few times per user preprogrammed into the system.

You can deactivate the license from one machine and reactivate in another by yourself if you have access to both machines as per -
