I lost Office 2019 after installing Windows 11

To download and reinstall Office 2019 after installing Windows 11, use the Microsoft account that was associated with the product key when Office 2019 was first redeemed.

1. Go to the Microsoft account dashboard: https://account.microsoft.com.
2. Sign in with the same Microsoft account that was used to activate Office 2019.
3. On the Overview or Services & subscriptions page, locate the Office 2019 product.
4. Select Install next to Office to download the installer.
5. When the download finishes, run the installer:
   • In Edge/Internet Explorer: select Open file.
   • In Chrome: select Setup.
   • In Firefox: select Save File, then run it.
6. Approve the User Account Control prompt by selecting Yes. The installation will begin.
7. When the message "You're all set! Office is installed now" appears, close the installer and start any Office app (such as Word or Excel).
8. Accept the license terms; Office should activate automatically using the signed-in Microsoft account. If prompted by the Activation Wizard, follow the on-screen steps.

If Office 2019 does not appear under the Microsoft account used, verify that the correct account is being used for sign-in (the one originally associated with the product key). If installation issues occur, use the steps in Troubleshoot installing Office.
