I am having trouble installing Office, Mac version. The issue is that the product key is invalid (per the message I get when I try to run anything) because the old version of office I had before left behind the old product key. Evidently it will not overwrite the product key if you are installing a new version, it try's to use the old key. I am going from 2004 to 2008, Office Pro. When I try to open, say Word all I get is a message saying the product key is invalid and to go to MS Office setup assistant for help, but there is nothing in the assistant to help.
How do I delete the old product key. I have deleted the old version of Office but the old product key is left behind somewhere.
Thanks
