Check for multiple copies of Office

Activation can fail if you have multiple copies of Office installed. Let's uninstall any versions of Office you aren't using before we continue to troubleshoot.

  1. Open Control Panel using the steps below for your operating system:

    • Windows 10 On the Windows 10 task bar, type Control Panel in the Type here to search box, select Control Panel in the search results, and then select Programs and Features.

    • Windows 8.1 or 8 Right-click the Start button Windows Start button in Windows 8 and Windows 10 (lower-left corner), select Control Panel, and then select Programs and Features.

    • Windows 7 Click Start > Control Panel > Uninstall a program.

  2. In the Search Programs and Features box (upper-right corner) of Programs and Features, search for the word office.

    You might see multiple versions installed, like this:

    If more than one version appears, right-click the version you aren't using and select Uninstall.

    If only one version is listed, you can go to Step 3: Check your Microsoft 365 subscription status.

  3. When the uninstall is finished, restart your computer.

  4. Open an Office app.

  5. If Office still won't activate, try running an online repair as described in Repair an Office application to fix up the remaining install of Office. If you still can't activate, proceed to the next step.
