Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hello,Phill D NC
Welcome to the Microsoft community!
I have realized that you are now unable to reinstall your Office 2016 in Window 7.
Since the installation path of Office is fixed and cannot be changed, Office cannot be installed when there are anomalies in the local files of Office, or when there are residual files that cause incorrect access to the data, as well as when there are problems with the system and the system registry.
Meanwhile your current problem is exactly the same as an Italian thread I encountered last month, though that user supposedly solved it by using an offline installer. I've also provided some options appropriately, so if you can, you can use the translation tool to check it out

Feel free to post back if you need further assistance.
Thank you for your understanding and patience and I look forward to hearing from you.
