Hi there @Esav4,
Welcome to the HP Support Forums! It is a great place to find the help you need, from other users, HP experts, and other support personnel. I understant that you are trying to transfer a software license from one computer to another. I am happy to give you a hand with this.
Please take a look through this document from Microsoft: "Copy". "Move" or "Transfer" an Office installation to another computer. - answers.microsoft.com
Beyond that, I would suggest you contact Microsoft Support - support.microsoft.com over this issue.
Please let me know whether that works for you, and if it does resolve your issue, please mark this post as a solution. Kudos would also be appreciated.
