license folder empty and need psim working on both home PC and laptop for senior design

orcotoo

Hello i have the 2025 version on my PC and works fine but i need the program on my laptop but I'm getting an error. Is there anyway to get the program working on both my laptop and my PC at home? Also, the license folder is empty for some odd reason after I downloaded the 2026 version fresh onto my laptop. The hidden checkbox is also not checked so I don't know where it is. Any help would be appreciated it!

Hi @orcotoo

The error "License was already activated using different HostID" means that the student edition license key has already been used on another computer or hardware setup.

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 –
