A family of Microsoft word processing software products for creating web, email, and print documents.
Run an Online Repair of Microsoft 365 or Office first; this is the recommended fix for the “Word has run into an error” message on Windows.^1^
Repair Microsoft Office
Close Word and all other Office applications, then:
Windows 11
- Right-click Start and select Installed apps.
- Find Microsoft 365 or Microsoft Office.
- Select the three dots (…) → Modify.
- Select Online Repair → Repair.
- Complete the prompts, restart the computer if requested, and try Word again.
Windows 10
- Right-click Start and select Apps and Features.
- Select Microsoft 365 or Microsoft Office.
- Select Modify.
- Choose Online Repair → Repair.
Online Repair repairs the entire Office installation, even when only Word is affected. If the installation offers only an MSI-based repair option, select Repair and then Continue.^2^
If only one document produces the error
The document itself may be damaged. After Word can open to a blank document:
- Select File → Open → Browse. Do not select the file from Recent.
- Select the affected document once.
- Select the arrow beside Open.
- Choose Open and Repair.^3^
If that fails, create a blank document and select Insert → Object → Text from File, then select the affected file. This may recover its text without importing the damaged final paragraph information.^4^
If Online Repair does not fix Word
Test Word without add-ins and global templates:
- Press Windows + R.
- Enter:
winword /a - Press Enter.
If Word opens this way, an add-in, template, or Word setting is likely involved. In Word, go to File → Options → Add-ins, select an add-in category under Manage, choose Go, and disable add-ins one at a time until Word starts normally.^4^
Also install available Office and Windows updates, restart Windows, and test again. If Word still fails after Online Repair and the /a test, uninstalling and reinstalling Office is the next recovery step.^1^
