Run a full Online Repair of the Office/Microsoft 365 installation, as the built‑in “repair now” prompt is often not sufficient.
On Windows 10 or 11:
- Right‑click the Start button.
- Select Apps and Features (or Installed apps in Windows 11).
- Find the Microsoft Office or Microsoft 365 product, select it, then choose Modify.
- In the How would you like to repair your Office Programs window, select Online Repair and then Repair. This performs a more thorough repair than Quick Repair.
- Follow the on‑screen instructions and let the repair complete, then try opening Word/Excel/Outlook again.
On Windows 8/8.1:
- Right‑click the Start button and select Control Panel.
- Under Programs, select Uninstall a program.
- Right‑click the Microsoft Office product and select Change.
- For Click‑to‑Run installations, choose Online Repair > Repair. For MSI‑based installs, choose Repair and then Continue.
- Complete the wizard and test the apps again.
If the error persists after an Online Repair, completely uninstall Office from Apps & Features/Programs and Features, restart the computer (not just shut down), then reinstall Office from the associated Microsoft account or organization portal.
