How to install Microsoft Office 2021 Professional Plus

Question

Hello,

I am trying to REINSTALL a version of MS Office Professional Plus 2021 that I had installed on this machine. I recently did a clear install of Windows 11 and when I try to install the .img file and activate using the same key I had, I receive the following error:

Error code: TOKEN_NOT_FOUND

Correlation ID: 5eef6d1b-a768-4ff6-b881-7ab307b7a39e

Either I have the wrong installation file or somehow my key stopped working - even though I was using the products it had installed previously within the past 24 hours.

Confirm the license status of your Microsoft Office product. If you had already activated it on the same machine and it stopped working after a Windows reinstall, it might be related to how Office licenses are tied to hardware. Make sure you are using the same machine and the same version of Windows that you initially used for activation.
