Vista - Faulty app Error loading Vista

Monday, February 12, 2007 Application n Error Faulting application
setup.exe, version 6.0.6000.16386, faulting module kernel32.dll, version

Hi, the error above is what I receive trying to install Vista....

Running WindowsSP SP2
Before I even purchased it I ran the vista upgrade advisor, only one issue
with my scanner,no biggie.
So I purchased Vista Home Premium upgrade
Backed up files I needed
Cleaned out any malware/adware using 2 different programs (none)
Ran a complete virus scan (none)
Deleted temporary files and cookies
Searched for tmp files and deleted them
Ran a window washer program
Reboot

After reboot I created a new restore point, disabled the virus program, put
the Vista cd in and got that message. I tried several times in both drive
bays.

Any suggestions?
Many thanks

PS: I also did a scandisk and defrag

TY
