Notes:
- This repairs the entire Office suite, even if only Word is failing.
- Quick Repair is faster, but Online Repair is more complete.
If Word still fails after Online Repair, start Word in Safe Mode to check whether an add-in is causing the crash:
- Press Windows + R.
- Type
winword /safeand press Enter. - If Word opens in Safe Mode, go to File > Options > Add-Ins.
- In Manage, select the add-in type and click Go.
- Clear one add-in at a time, restart Word normally, and test again.
If Word does not open in Safe Mode, repair Office again or reinstall Office.
