A family of Microsoft word processing software products for creating web, email, and print documents.
Run a full Online Repair from Windows Settings rather than using only the Repair button shown in Word’s error message.
1. Repair Microsoft Office
An Internet connection is required for Online Repair.
Windows 11
- Right-click Start and select Installed apps.
- Find Microsoft 365 or Microsoft Office.
- Select the three dots (…) next to it, then select Modify.
- Select Online Repair → Repair.
- Complete the prompts, restart the computer, and open Word.
Windows 10
- Right-click Start and select Apps and Features.
- Select Microsoft 365 or Microsoft Office.
- Select Modify.
- Select Online Repair → Repair.
- Complete the repair and restart the computer.
This repairs the entire Office installation, even when only Word is affected. If the installer offers only Repair and Continue, select those options instead; that indicates an MSI-based Office installation.^1^
2. If Word still does not open, test Safe Mode
- Press Windows key + R.
- Enter:
winword /safe
- Select OK.
If Word opens and its title bar says Safe Mode, an add-in may be preventing normal startup.^2^
To isolate it:
- In Word, select File → Options → Add-ins.
- At the bottom, select COM Add-ins under Manage, then select Go.
- Clear one add-in and select OK.
- Close Word and open it normally.
- Repeat until Word opens normally; leave the problematic add-in disabled or install an updated version.^3^
If Word does not open in Safe Mode after Online Repair, the next supported path is to uninstall and reinstall Office.^3^
