After doing an in place upgrade from Win 7 ultimate to Windows 10 - everything worked great except when I try and run Office Pro 2013 plus I get informed that I need a new product key and that my current key is invalid. I have uninstalled Office and reinstalled and get the same error - office shuts down immediately.
Irony is that Office is the only product that failed after the upgrade.
thanks for any help
regards
Michael
