    Try these steps in order:

    1. In any Office app, go to File > Account > Update Options > Update Now.
      • If Update Now is not shown, select Enable Updates first.
      • Wait until Office finishes checking and installing updates.
    2. If the app opens but shows Product Deactivated, select Reactivate and sign in when prompted.
      • If that does not work, sign out of all Microsoft 365 apps, including Outlook, close them, restart an Office app, and sign in again.
    3. Check whether a proxy setting is blocking activation:
      • Open Start > Settings > Network & internet > Proxy.
      • In Automatic proxy setup, review whether automatic detection or a setup script is enabled.
      • In Manual proxy setup, make sure a proxy server is not enabled unless it is required.
      • If the device is used for both home and work, proxy settings can affect Microsoft 365 installation and activation.
    4. Repair Office:
      • Open Control Panel > Programs > Programs and Features.
      • Right-click Microsoft Office or Microsoft 365 and select Repair or Change.
      • Follow the prompts.
      • In Windows 11, app repair is also available from Start > Settings > Apps > Apps & features > app Advanced options > Repair.
    5. If the apps still fail to start or show a stopped working error, update Windows and device drivers:
      • Windows 11: Start > search settings > Windows Update > Check for updates.
      • Windows 10: Start > Settings > Update & security > Windows Update > Check online for updates from Microsoft Update.
      • Also update video card, printer, mouse, and keyboard drivers from the device manufacturer if needed.
    6. If the problem continues, uninstall and reinstall Office using the Microsoft uninstall troubleshooter. If the troubleshooter does not fully remove Office, manual uninstall is available.

    If the error specifically says Product Deactivated, an admin licensing change can trigger it. Common causes include license reassignment, group-based licensing changes, or the Latest version of Desktop Apps service plan being turned off. In that case, use Reactivate first, then check with the admin if the issue returns.

    Hi, first open Excel >> File >> Account and make sure you’re signed in with the account linked to your Office license.

    If you purchased Office yourself, check that your Office product or active Microsoft 365 subscription appears here: https://account.microsoft.com/services

    If it still fails, please share a screenshot of the exact licensing error and the Office product name under File >> Account. Hide your email address and any product key.

    Let me know what you find, and I’ll help with the next step.
