We're sorry that Office setup isn't working as expected. While we investigate this issue, here are some things you can try to fix the problem:

  • Try closing the error message. Office might activate successfully after the message is closed.

  • In an Office app, open a new document and then go to File > Account > Update options > Update now. This will install the latest updates, which may fix the issue. For help with updating Office, see Install Office updates.

  • If Office doesn't activate, follow the instructions in Repair an Office application. Be sure to select the option for Online Repair.

  • Did your Microsoft 365 subscription or trial expire? Check your subscription status by going to your Services & subscriptions page. If you see your subscription under Canceled subscriptions, you'll need to renew using the Renew link on the Services & subscriptions page.

  • There may be a conflict with multiple versions of Office installed on your PC. It's possible that Microsoft 365 came pre-installed on your Windows PC and might need to be uninstalled so you can use your own copy of Office.

    1. On the Windows task bar, type Control Panel in the Search box and press Enter.

    2. Select Uninstall a program (Category view) or select Programs and Features (Large or Small icon view.

    3. In the upper-right corner of the Uninstall or change a program box, type Office in the Search programs or features box.

    4. Check to see if more than one version of Office is listed. Microsoft 365 is often pre-installed on new Windows computers. If this isn't the version that you're trying to use, right-click it and select Uninstall.

  • Close and re-open any Office app and start the process again. If that doesn't work, wait awhile and try again.

If none of the steps above work, do this:

Use the uninstall troubleshooter to uninstall Microsoft 365, Office 2021, Office 2019, or Office 2016 from your Windows PC.

  1. Select the button below to start the uninstall troubleshooter.

    Uninstall

  2. Click Open if you get a pop-up window indicating This site is trying to open Get Help.

  3. Follow the prompts on the remaining screens and when prompted, restart your computer.

  4. Select the steps for the version of Office you want to install or reinstall.

    Microsoft 365 | Office 2024 | Office 2021 | Office 2019 | Office 2016

Important: 

  • The uninstall troubleshooter currently can't uninstall Office 2024.

  • Run the troubleshooter on the same Windows PC with the Microsoft 365 or Office product you want to uninstall.

  • You need to be on Windows 10 or higher to run the troubleshooter.

Tip: If the Microsoft 365 uninstall troubleshooter doesn't completely uninstall Microsoft 365 or Office from your PC, you can try to manually uninstall Office.

If you're still having problems, you can contact Microsoft support.
