Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Donald,
I understand that you are getting an error activating Office.
You may run to the license removal tool by downloading and installing it through this link: https://support.microsoft.com/en-us/microsoft-365-activation-licensing/how-to-remove-office-license-files-on-a-mac
However, before running the license removal tool application make sure to sign out your account on all the Office application and make sure that all Office application are closed then once done, you may now run the license removal tool.
