    For Windows 11, reinstall Microsoft 365 this way:

    1. Go to the Microsoft account dashboard and sign in with the Microsoft account used for Microsoft 365.
    2. Select Subscriptions in the left pane.
    3. On the Subscriptions page:
      • If using Microsoft 365 Personal, select Install Microsoft 365 in the upper-right.
      • If using a perpetual Office product, find it under Products you've purchased and select Install.
    4. In the install dialog:
      • Choose the language.
      • Choose the version if prompted.
      • Select Install.
    5. Download OfficeSetup.exe.
    6. Double-click the installer and complete setup.
    7. After installation, open Word or Excel while connected to the internet.
    8. If prompted, sign in with the same Microsoft account to activate Office.

    If Office was removed after a Windows recovery or reset, reinstall it using the steps in the ReadMe file copied to the desktop after recovery, or use the standard reinstall steps above.

    If reinstalling on the same device and Office is still partially installed or not working correctly, uninstall it first. Microsoft also provides an uninstall troubleshooter for Microsoft 365, Office 2021, Office 2019, and Office 2016 on Windows 10 or later. Restart the PC when prompted, then reinstall.

    If the apps are installed but one app is broken, Windows 11 also supports repair:

    1. Right-click Start > Installed apps.
    2. Find the Microsoft 365 or Office product, select the ellipses, then Modify.
    3. For Click-to-Run installs, select Online Repair > Repair.

    Hii ,

    Please be aware that there is currently an outage affecting Microsoft 365 services, which may also be impacting the download of the Office suite via the setup installer.

    If you previously had an Office suite installed, please ensure it is completely uninstalled first:

    Try performing the installation using the offline installer:

    Office 365 and 2024: https://officecdn.microsoft.com/db/492350F6-3A01-4F97-B9C0-C7C6DDF67D60/media/en-US/O365HomePremRetail.img

    Once the download is complete, disconnect from the internet, right-click the file, and select "Mount." Then, open File Explorer, go to "Computer" (or "This PC"), locate the Office icon, right-click it to open the Office folder, and run the "setup64.exe" file.

    Please consider rating this response, and feel free to visit the Microsoft Q&A community if you have any further questions.

    Thanks.
