Transferring office for Mac from one computer to another

Office 16.55 is the version number for a number of different Office products.

If you have the Office 365 subscription service, then you can download office and log in with your account to activate it. But you will need the Family version to use it on more than one computer.

If you have the Office 2019 or 2021 one time purchase version, you will need the original installer and product key to install it on your husband's Mac.

We have no idea:

1. What model year of computers?
2. Versions of Mac OS installed on them?
3. Version of Office for Mac installed on your computer?

Got it, however I am no longer interested in assisting as you think asking clarifying questions is rude.

Good luck.
