Student License Activation Error - "Already activated using different HostIDs"

Toxical1402

Dear Altair Support Team,

I'm a student using a free student license for Altair EDEM.

Due to an unexpected system malfunction, my computer encountered a critical error and required a hard reset, which involved reinstalling Windows 11. As a result, some system data and settings were affected. After reinstalling Windows, I encountered the following error when attempting to activate my license:

"Error activating license: This license was already activated using different HostIDs."

I would greatly appreciate it if you could advise me on how to resolve this matter or suggest any appropriate solution.

Thank you very much for your time and support. I look forward to your guidance.

HI,

Your previous license key activation is now deactivated in Altair one, you can now reactivate the student license with the same license key.

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 –
