    If clicking the 'Repair Now' button does not resolve the problem, that performs a quick repair, that rarely resolves the problem, the best option is to perform a full online repair, this process basically reinstalls Office, please ensure you are connected to the Internet while the process is running.

    Before performing this process, please log into your Microsoft account on this link (https://account.microsoft.com/services/) and check to ensure your Office licence or Microsoft 365 subscription is listed correctly on your account.

    Open the Settings App (gear icon on your Start Menu)

    Go to Apps - Installed Apps, then scroll down to find Microsoft Office

    Select that and choose Modify - Online Repair

    That should fix any issues with your Office Installation.

    Try these steps in order:

    1. Select Repair Now in the error dialog first.
    2. If Word or Excel still does not open, run an Office repair from Windows:
      • Select Start
      • Type Control Panel and open it
      • Go to Programs > Programs and Features
      • Select the Microsoft Office product
      • Choose Change
      • Select Quick Repair and then Repair
    3. If the apps still fail, test whether an add-in is causing the crash by starting in Safe Mode:
      • Press Windows + R to open Run
      • For Word, type winword /safe and press Enter
      • For Excel, type excel /safe and press Enter
    4. If the app opens in Safe Mode, disable add-ins one at a time:
      • In the app, go to File > Options > Add-Ins
      • In the Manage list, select the app add-ins or COM Add-ins, then select Go
      • Clear one add-in, select OK, and restart the app normally
      • Repeat until the problematic add-in is identified
    5. If the app does not open even in Safe Mode, update Windows to get the latest drivers and fixes:
      • On Windows 11: Start > type settings > Windows Update > Check for updates
      • On Windows 10: Settings > Update & security > Windows Update > Check online for updates from Microsoft Update
    6. If the problem continues, use the Microsoft uninstall troubleshooter to remove Office completely, then reinstall it. Note: this removes Office from the PC, so save work and close apps first.
