Repair an Office application

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 (lower-left corner), and select Programs and Features on the pop-up menu.

    Right click the Start Menu
  2. Right-click the Microsoft Office product you want to repair, and select Change.

    Note: You'll repair the entire Office suite even if it's just a particular application you want to repair such as Word or Excel. If you have a standalone app, then you can search for the application by name.

  3. From the "How would you like to repair your Office Programs" screen, select Online Repair to make sure everything gets fixed, and then select Repair. The Quick Repair option is also available, which runs faster but only detects and then replaces corrupted files.

    Note: If your copy of Office is MSI-based, select Repair and then click Continue. If you need help figuring out if your Office is Click-to-Run or MSI-based, see below.

  4. Follow the instructions on the screen to complete.

Is my Office 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.

Running Repair didn't help. Now what?
