A family of Microsoft word processing software products for creating web, email, and print documents.
If Word and Excel say they need repair, do a full Office repair from Windows settings. The repair button inside the error dialog is usually only a quick repair and often does not fix the problem.
For Windows 11:
- Right-click Start.
- Select Installed apps.
- Find Microsoft 365 or Office.
- Click the three dots next to it, then select Modify.
- If prompted, choose:
- Online Repair > Repair for a full repair, or
- Quick Repair first if preferred, but Online Repair is the more complete fix.
- Follow the on-screen steps.
- Restart the computer if prompted.
For Windows 10:
- Right-click Start.
- Select Apps and Features.
- Select Microsoft 365 or Office.
- Choose Modify.
- Select Online Repair > Repair.
- Follow the on-screen steps.
- Restart the computer if prompted.
Important:
- This repairs the entire Office suite, not just Word or Excel.
- If there is a standalone Word or Excel app installed, select that app by name.
- If the installation is MSI-based instead of Click-to-Run, choose Repair and then Continue.
If files are opening in the wrong Office app after repair, reset the file association in Control Panel > Programs > Default Programs.
