Today office 365 has been giving me the following error:

"We're sorry, but Word has run into an error that is preventing it from working correctly. Word will to be closed as a result.

Would you like us to repair now?"

Similar error in Excel and Outlook... I've spent several hours trying to resolve this error.

Registry, Fresh install of Office 365, online/local repair, revert to older versions, etc...

Nothing is working. Any assistance is greatly apprciated.

This worked:

  1. Uninstall Office: First, uninstall Office from "Apps & Features" or "Programs and Features".
  2. Delete folders: Manually delete any remaining folders in these locations:
    • C:\Program Files and C:\Program Files (x86)
      • C:\ProgramData
        • C:\Users\%USERNAME%\AppData\Local\Microsoft
          • C:\Users\%USERNAME%\AppData\Roaming\Microsoft
  3. Clean the registry: Use caution when editing the registry. Navigate to HKEY_LOCAL_MACHINE\Software\Microsoft and HKEY_CURRENT_USER\Software\Microsoft, and delete any keys related to Office.
  4. Restart your computer: Reboot your PC to complete the process

    To resolve the error you're encountering with Office 365 applications like Word, Excel, and Outlook, you can try the following troubleshooting steps:

    1. Run as Administrator: Close all Office applications. Right-click on the Office app (e.g., Word) and select Run as administrator. Then, check if the issue persists.
    2. Microsoft 365 Activation Troubleshooter: Use the Microsoft 365 activation troubleshooter to help resolve activation issues. Make sure you are using the same Windows device where Office is installed. You can find this troubleshooter in the Get Help app on your device.
    3. Repair Office: Since you mentioned trying repairs, ensure you are using both the online and local repair options. Go to Control Panel > Programs > Programs and Features, select your Office installation, and choose Change to access the repair options.
    4. Check for Updates: Ensure that your Office applications are up to date. Go to any Office app, click on File > Account > Update Options > Update Now.
    5. Reset Microsoft 365 Activation State: If the problem persists, consider resetting the activation state for Microsoft 365 Apps for enterprise. Instructions can be found in the Microsoft documentation.
    6. Uninstall and Reinstall: If none of the above methods work, you may need to uninstall Office completely using the Microsoft 365 Uninstall troubleshooter, restart your device, and then reinstall the correct version of Office.
    7. Check Subscription Status: Ensure that your Microsoft 365 subscription is active and that you have the necessary licenses assigned. You can check this in the Microsoft 365 Admin Center under Billing > Your products.

    If these steps do not resolve the issue, consider reaching out to Microsoft Support for further assistance.
