A family of Microsoft word processing software products for creating web, email, and print documents.
Run an Online Repair of Microsoft Office from Windows Settings; it is more thorough than the repair button shown in Word’s error message.
Repair Microsoft Word
- Close Word and all other Office applications.
- Open the repair settings:
- Windows 11: Right-click Start → Installed apps.
- Windows 10: Right-click Start → Apps and Features.
- Find Microsoft 365 or Microsoft Office.
- On Windows 11, select the three dots beside it, and then select Modify. On Windows 10, select the product and then Modify.
- Choose:
- Online Repair → Repair for a Click-to-Run installation.
- Repair → Continue if the window identifies an MSI-based installation.
- Follow the prompts, restart the laptop when finished, and open Word again.
This repairs the entire Office suite, even when only Word is affected.^1^
If Word still cannot open
Test whether an add-in is preventing Word from starting:
- Press Windows + R.
- Enter:
winword /safe - Select OK.
- If Word opens and its title bar shows 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 at a time, select OK, and restart Word normally. Older add-ins such as ABBYY FineReader and Dragon Naturally Speaking can cause startup problems.^2^
If Word does not open in Safe Mode, the issue is unlikely to be an add-in; proceed to reinstall Office.
Reinstall Office if repair fails
- Before uninstalling, ensure that the Microsoft account or work/school account associated with your Office license is available.
- Open Installed apps or Apps and Features again.
- Select Microsoft 365 or Microsoft Office → Uninstall.
- After removal, sign in to the Microsoft 365 Apps page using the account associated with Office.
- Select Install apps, run the downloaded installer, and follow the prompts.^3^
If this is a company or school laptop and Modify or Uninstall is unavailable, an administrator may need to perform the repair or reinstall.
