A family of Microsoft word processing software products for creating web, email, and print documents.
Run Online Repair for Microsoft Office; it repairs the entire Office installation, including Word, and is more thorough than the repair offered in the error message.
Repair Microsoft Word
- Close Word and all other Office applications.
- Right-click Start:
- Windows 11: select Installed apps.
- Windows 10: select Apps and Features.
- Find Microsoft 365 or Microsoft Office.
- Select the three dots beside it, and then select Modify.
- If prompted by User Account Control, select Yes.
- Choose:
- Click-to-Run installation: Online Repair → Repair.
- MSI installation: Repair → Continue.
- Complete the on-screen instructions, restart the computer if requested, and then open Word. Online Repair affects the entire Office suite, not only Word.[^1^](https://support.microsoft.com/office/-something-went-wrong-error-when-you-try-to-start-a-microsoft-365-app-4b4471dd-cf86-4a37-910d-35a01a6c7d17#windows-10 ""Something went wrong" error when you try to start a Microsoft 365 app")
If Word still displays the error
Test whether an add-in is causing the startup failure:
- Press Windows key + R.
- Enter:
winword /safe - Select OK.
If Word opens in Safe Mode:
- Go to File → Options → Add-ins.
- At the bottom, select COM Add-ins under Manage, and then select Go.
- Clear one add-in, select OK, and restart Word normally.
- Repeat until Word opens normally. Leave the problematic add-in disabled or obtain an updated version from its publisher.
If Word does not open in Safe Mode, add-ins are unlikely to be the problem.[^2^](https://support.microsoft.com/office/lifecycle/i-get-a-stopped-working-error-when-i-start-office-applications-on-my-pc "I get a "stopped working" error when I start Office applications on my PC | Microsoft Support")
Final fallback
If Online Repair does not fix Word:
- Install available updates from Settings → Windows Update → Check for updates.
- If the error continues, uninstall Microsoft 365 or Office using Microsoft’s uninstall troubleshooter.
- Restart the computer when prompted.
- Reinstall Office from the Microsoft account associated with the license.
Microsoft recommends uninstalling and reinstalling when Word cannot start in Safe Mode and Office repair does not resolve the failure.[^2^](https://support.microsoft.com/office/lifecycle/i-get-a-stopped-working-error-when-i-start-office-applications-on-my-pc "I get a "stopped working" error when I start Office applications on my PC | Microsoft Support")
