Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
I do have the same issue.
I am trying to install Visio 2016 Professional becayuse it is the only license I have, but in my case, I have MS Office 2021 installed.
How can I solve the error?
Update: Hey, if someone else has this same error, this is fixed by uninstalling all the office software and start installing everything again, but starting from the oldest software to the newest. Installing older software while having newer releases/versions, causes this error.
Hope this helps.
