After Ultimate Upgrade Problems

I just upgraded Vista Home Premium to Vista Ultimate and the problems began.

It upgraded fine with no problems, but now half the programs that I try to
open receive an error of:

"This application has failed to strat because its side-by-side
configuration is incorrect. Please see the application event log for more
detail"

When I try to start Microsoft Outlook in Office 2007, it comes up with
preparing to install, and then says another installation is already running,
please wait until it finishes then try again, but no installation is running.

Anyone have any ideas?

Thanks,

Bob Redwitz
