Try these steps in order:
- Update Office
- Open any Office app.
- Go to File > Account.
- Under Product Information, select Update Options > Update Now.
- If Update Now is not shown, select Enable Updates first.
- Run Office in Safe Mode to check add-ins
- Press Windows + R to open Run.
- For Excel, type:
excel /safe
- If Excel opens in Safe Mode, go to File > Options > Add-Ins.
- In Manage, select the add-ins type and click Go.
- Clear one add-in at a time, click OK, then restart Excel normally.
- Older add-ins such as ABBYY FineReader, PowerWord, and Dragon Naturally Speaking are known to cause problems.
- Repair Office
- Right-click Start and select Apps and Features.
- Select Microsoft 365 or Office.
- Select Modify.
- Choose Online Repair > Repair.
- This repairs the full Office installation. A restart may be needed after repair.
- Install Windows updates and device drivers
- In Windows 10: Start > Settings > Update & security > Windows Update.
- Select Check online for updates from Microsoft Update.
- Install available updates.
- If the issue continues, update drivers for the video card, printer, mouse, and keyboard from the device manufacturer.
- Uninstall and reinstall Office
- If repair does not fix the issue, use the Microsoft uninstall troubleshooter to remove Office.
- Restart the PC after uninstall.
- Reinstall Office using the install steps for the Office version on the PC.
- Note: the uninstall troubleshooter cannot uninstall Office 2024 and requires Windows 10 or higher.
If the Repair Now button in the error box appears, it is reasonable to try that first. If the problem returns, use Online Repair from Apps and Features, because it is the more complete repair option.
