Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi,
If you have used this Microsoft license before, it is permanently tied to your Microsoft account. To reinstall Office on that laptop, log in to your Microsoft account here: https://account.microsoft.com/services
Note: If you cannot find the license on that account, it may be tied to a different Microsoft account. You will need to identify the specific account associated with the license to install and activate Office.
Once you identify the correct account, 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, and sign in using the Microsoft account associated with the purchase to activate Office.
