I lost Microsoft 365 on my computer, cannot look at Excel or word documents. Was trying to do repair office apps thru appwiz, tried Quick repair, did not work. Then tried Online repair and program was removed.

Microsoft 365 and Office | Word | For home | Windows

    Hi Robert,

    If the full online repair removed Office from your PC, when you activated Office that licence should have become associated to your Microsoft Account as a digital licence online and it is from there that you can re-install Office without the need for a product key:

    https://account.microsoft.com/services/

    Do you find your Office licence linked to your account on that link and are you able to reinstall Office from there, if not, where did you purchase your Office licence.

    If Online Repair removed Microsoft 365, the next supported step is to reinstall it.

    1. Restart Windows.
    2. Reinstall Microsoft 365 from the Microsoft account services page: https://account.microsoft.com/services/
    3. After installation finishes, try opening Word or Excel.
    4. If the apps still do not open, run a repair again:
      • Windows 11: Start > Installed apps > find Microsoft 365 or Office > ... > Modify
      • Windows 10: right-click Start > Apps and Features > find Microsoft 365 or Office > Modify
    5. In the repair window:
      • Try Quick Repair first.
      • If that does not fix it, use Online Repair.
    6. Restart the computer after the repair if prompted.

    Important details:

    • Repair applies to the entire Office suite, not just Word or Excel.
    • Online Repair needs an active internet connection.
    • If repair does not resolve startup problems, uninstalling and reinstalling Office is the next step.
