To help isolate the issue:
Are you using the same Office 2024 license on two different computers?
Please note that Office Home 2024 is a one time purchase license that can only be installed and activated on one PC.
Are you signed in to your computer with the same Microsoft account associated with the license? You can double check here: https://account.microsoft.com/services
Also, can you tell me the exact name of your Office license?
