I have a product key for my Home and business pack that I installed last week but i think something went wrong, so can I uninstall and reinstall again on the same PC using the same product key or I only allow to use 1 time only?

Microsoft 365 and Office | Install, redeem, activate | For home | Windows

    When you first installed and activated Office that licence should have become associated to your Microsoft Account as a digital licence online and it is from there that you can re-install Office without the need for a product key:

    https://account.microsoft.com/services/

    Do you find your Office licence listed on your account there.
