    Virginia,

    In order for anyone to come up with a reasonable solution, more information is needed.

    Is this installed on Windows 11?

    Which subscription do you have, Microsoft 365 basic, personal, family, or premium?

    What exactly is the "not working" behavior? What is the error message, if any?

    If Microsoft 365 installed but Word and Excel still can’t be used, try these steps in order:

    1. Repair Microsoft 365 on Windows
      • Right-click Start.
      • In Windows 11, select Installed apps. In Windows 10, select Apps and Features.
      • Select the Microsoft Office product.
      • Select Modify.
      • In the repair window, choose Online Repair > Repair.
      • Complete the repair and then try opening Word or Excel again.
    2. If Office shows Account Notice or Unlicensed Product
      • This can happen if the installed Office version does not match the current Microsoft 365 plan.
      • Use the uninstall troubleshooter to remove Office, restart the PC, and then reinstall the version that comes with the subscription.
      • Note: the uninstall troubleshooter requires Windows 10 or higher and must be run on the same PC.
    3. If an app says it “stopped working” when opened
      • Install the latest Office updates first.
      • Older add-ins can cause this problem.
    4. If the install itself may not have completed correctly
      • Run the Microsoft 365 setup troubleshooter from Get Help.
      • Follow the prompts and restart the computer when prompted.
    5. If the problem continues
      • Contact Office Support.
