Problems changing Home & Business key from Office 2010 Pro Plus
First off if this is the wrong way to post please forgive as I'm a complete novice.
I have a laptop that was legally covered using Office 2010 Professional Plus (via company MS action pack but is no longer legit.
I've probably caused the problem by trying to be honest.
I have purchased a DVD copy of Office 2010 Home and Business and am trying to NOT uninstall all of the Prof Plus for fear of messing up outlook and server settings. I have tried using add/remove program change key but it says I have an invalid key. I am guessing what it is saying it is invalid for Prof Plus. I have removed all of the applications that are not part of Office 2010 Home and Business.
Any suggestions please would be gratefully recieved.
