Yes. If Word is repaired successfully, it should open normally without showing the same repair/error message again. Since the same error box keeps returning, the repair that ran did not fully fix the problem.
Try this in order:
- Restart the PC.
After restart, sign in again and try Word.
- Run a full Office repair.
In Windows:
- Right-click Start and open Apps and Features or Installed apps.
- Select Microsoft 365 or Office.
- Choose Modify.
- If available, select Online Repair and then Repair.
Online Repair is more complete than Quick Repair. Quick Repair only detects and replaces corrupted files.
- Test Word in Safe Mode.
- Press Windows + R.
- Type
winword /safe and press Enter.
- Confirm the title bar shows Word (Safe Mode).
- If Word opens in Safe Mode, disable add-ins.
- In Word, go to File > Options > Add-Ins.
- In the Manage list, select Word Add-ins or COM Add-ins, then select Go.
- Clear one add-in, select OK, then restart Word normally.
- If Word opens normally, the disabled add-in is the cause.
- If Word does not open in Safe Mode, repair Office again or reinstall Office.
The documented guidance is that if the app does not start in Safe Mode, the issue is not with add-ins.
- If the problem is only with one document, try opening the file with Open and Repair.
- In Word, select File > Open > Browse.
- Select the file.
- Select the arrow next to Open.
- Select Open and Repair.
For Word specifically, there is also a troubleshooting startup switch:
- Press Windows + R
- Type
winword /a
- Press Enter
That starts Word without loading add-ins and global templates automatically. If Word works that way, the problem is likely related to startup customizations.
If needed, there are Word registry reset steps for the Data and Options keys, but those should be used carefully because incorrect registry changes can cause serious problems and reset Word settings.
