Run an Online Repair of Microsoft 365 from Windows 11 Settings rather than relying on the Repair Now button displayed by Word.
1. Run Online Repair
Before starting, confirm that Microsoft 365 or Office appears under your Microsoft account’s Services & subscriptions, because Online Repair may reinstall Office.^1^
- Save your work and close all Office applications.
- Right-click Start and select Installed apps.
- Find Microsoft 365 or Microsoft Office.
- Select the three dots (…) beside it, then Modify.
- For a Click-to-Run installation, select Online Repair > Repair.
- Do not select Quick Repair; Online Repair is the more thorough option.
- If the installer instead shows an MSI-based Change your installation screen, select Repair > Continue.
- Complete the prompts, restart the laptop, and test Word by creating a blank document and opening an existing document.
This repairs the whole Office suite even though only Word is failing.^2^
2. If Word still cannot open documents
Test Word in Office Safe Mode:
- Press Windows key + R.
- Enter:
winword /safe
- Select OK, then try opening a document.
Safe Mode starts Word without automatically loading certain add-ins and customizations.^3^
If documents open in Safe Mode:
- In Word, select File > Options > Add-ins.
- At the bottom, set Manage to COM Add-ins, then select Go.
- Clear the add-in checkboxes and restart Word normally.
- Re-enable add-ins one at a time until the problem returns; leave the problematic add-in disabled.^4^
If Word fails even in Safe Mode after Online Repair, uninstall Microsoft Office from Control Panel > Programs > Programs and Features, restart Windows, and reinstall Office from the Microsoft account associated with the license.^5^
