Hi! Santiago Nuñez3,
Thank you very much for your reply and the information you have provided!
I noticed you mentioned that you first installed Office under the Enterprise account status, and since Office applications store your activation information locally, it does have the potential to have an impact on this.
For now I suggest you try resetting Office through the registry first, here are the detailed steps:
Press Windows + R , type in: regedit in the run box that opens and press enter.
Rename the Office folder by locating the following key (right-click on it and select Rename, e.g. rename Office to Officeold)
HKEY_CURRENT_USER\Software\Microsoft\Office
Then reopen the word document to see if it worked.
Disclaimer: Generally, modifying registry subkeys or work group is intended for advanced users, administrators, and IT Professionals. It can help fix some problems, however, serious problems might occur if you modify the registry incorrectly. Therefore, make sure that you follow these steps carefully. For further protection, back up the registry before you modify it. Then, you can restore the registry if a problem occurs. For more information about how to back up and restore the registry, click How to back up and restore the registry in Windows - Microsoft Support to view the article.
If the above reset method doesn't work, you need to uninstall the Office application and reinstall it:
- Uninstall the Office applications in your computer, I noticed that you have installed a version of Click -to-Run, please refer to the official instructions link: Uninstall Office from a PC - Microsoft Support, Uninstall Office by following the Click -to-Run version of the uninstallation in the page.

- After completing the uninstallation, please click the link: Microsoft account | Services & subscriptions, Log in to your Microsoft account that is subscribed to Microsoft 365, click on Services & Subscriptions on the left hand side of the page, find your Microsoft 365 subscription on the right hand side, where there will be an install button, please click on it to install the Office apps that match your subscription. See if your problem is resolved after reinstalling Office applications.
Thank you for your efforts on this issue!
Feel free to post back if you need further assistance.
Thank you for your understanding and patience and I look forward to hearing from you.
