If an Office application such as Word or Excel isn’t working correctly, sometimes restarting it will fix the problem. If that doesn’t work, you can try repairing it. When you’re done, you might need to restart your computer.

Repair Office from the Control Panel

The steps to access the repair tool vary depending on your operating system. Choose your operating system from the tabs below:

  1. Right-click the Start button Windows Start button in Windows 8 and Windows 10  and in Windows 11 select Installed apps, or in Windows 10 select Apps and Features on the pop-up menu.

  2. Select the Microsoft Office product you want to repair and select Modify. If you don't have any options, select the three dots on the side.

    Note

    This will repair the entire Office suite even if it's just one application you want to repair such as Word or Excel. If you have a standalone app installed, then search for that application by name.

  3. In the How would you like to repair your Office Programs window, select Online Repair > Repair to make sure everything gets fixed. (The faster Quick Repair option is also available, but it only detects and then replaces corrupted files.)

  4. Follow the instructions on the screen to complete the repair.

Is my Office installation Click-to-Run or MSI-based?

  1. Open an Office application, such as Outlook or Word.

  2. Go to File > Account or Office Account.

  3. If you see an "Update Options" item, you have a Click-to-Run installation. If you don't see the "Update Options" item, you have an MSI-based install.
