Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
I suggest you to refer to the section 'Stop the pop-ups to try, buy, or activate Office' from this article and check:
Hope it helps.
Basically, I have to reinstall the Office?
Tried to "Repair" with control panel but it was not fixed.
Then, I had read the reinstall method, and checked up on My Office Account and it brought me to the loop initial page. None of the options are now applicable.
* Please be informed, I didn't install nor activate Office... I thought it was purchased along the PC. Although, I've linked Microsoft Account with Windows and Office. No Activation Key is with me. So, reinstalling it is a risk of losing Office which (may) included with my PC purchase.
