Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi
I have never donne this before, so you should have much work and get frustated if not solve your problem, but you can try it!
For me this problem is related to:
1 - Bad Instalation Media
2 - Some Registry keys that you have to delete, but i don't have a clue, wait to see if someone could now.
