    May I ask why you want to reinstall? If something is not working, try a Quick Repair first; see https://support.microsoft.com/en-us/office/lifecycle/repair-an-office-application .

    If a Quick Repair does not work, please elaborate on the symptoms that you see.

    Hi,

    To reinstall Office, sign in to your Microsoft account here: https://account.microsoft.com/services

    Can you find the subscription? If yes, locate Microsoft Office and click Install

    This will download the Office installer

    Run the installer and follow the on-screen instructions

    Once installed, open any Office app such as Word or Excel, then sign in using the Microsoft account associated with the purchase to activate Office.

    If Microsoft 365 or Office was just uninstalled, the recommended next step is to reinstall it from the account that is linked to the purchase or subscription.

    1. Go to the Microsoft account dashboard and select Sign in.
    2. Sign in with the same Microsoft account used to set up Microsoft 365 or Office.
    3. Open Subscriptions.
    4. On the Subscriptions page:
      • For a perpetual Office product, find the same product name under Products you've purchased and select Install.
      • For Microsoft 365 Personal, select Install Microsoft 365.
    5. In the install dialog:
      • Choose the language.
      • Choose the version.
      • Select Install.
    6. Download OfficeSetup.exe.
    7. Double-click the installer to start installation.
    8. When You're all set appears, select Close.
    9. Stay connected to the internet, then open Word or Excel.
    10. In most cases, activation completes when the app opens and the license terms are accepted. If prompted, sign in with the Microsoft account to activate.

    If the install option is not visible after signing in, check that the correct account is being used.

    An offline install is also available:

    1. From the same Install Microsoft 365 dialog, choose Offline installer from Choose a version.
    2. Download the .img file.
    3. Double-click the file to mount it.
    4. Open the Office folder.
    5. Run Setup32.exe or Setup64.exe.
