Unable to Deactivate on Crashed macOS After Recovery

19225074

My Mac recently crashed, and I had to reinstall macOS. Unfortunately, I no longer have access to the previous installation of AI Studio, so I am unable to deactivate the license tied to that system.

When I attempt to activate the license on my newly restored system, I receive the following error:
"Error activating license: This license was already activated using different HostIDs."

I didn't back up the license file before the crash. Is there any way to reactivate the license?

HI @19225074

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 –
