Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello JAMES M,
Welcome to Microsoft Community.
I am a Microsoft user just like you, I hope you are doing well.
Sorry for this inconvenience. However, you will need to provide additional information to allow me to understand your inquiry.
Please understand that support for Office 2013 has ended: https://support.microsoft.com/office/90e4b0d1-098f-4656-b6e7-8b13b67ed62f
Also, Office Professional Plus is a volume license that requires a product key to activate, if you have the product key, you can activate your license.
I await your response.
