Vista - Cannot Install RC1 on HP Pavilion Notebook PC

I am trying to install RC1 (from the MS CD) on an HP Pavilion dv5120us
Notebook PC.

During the compatibility check, installation stops and the dialog instructs
me to go to "Programs" and uninstall "HP ProtectTools Security Manager." The
problem is this program does not exist when surveying the programs under
Start/All Programs or under A/R P. I find no reference to this program in
the User Guide or on HP's website.

I contacted HP support and they recommended removing the file "hpqwmi.exe."
This file was not located in Startup or "C:\Program Files\HPQ\SHARED\" per
their feedback. Furthermore after running a file search for this file it was
not located on my computer!

After informing them of the above, their only other suggestion was "At this
point of time, to resolve the issue I recommend you to format the hard drive
and then proceed with the installation of Vista Operating System in your
notebook. You may format the hard drive using 'killdisk'utility."

Has anyone else encountered such a problem with installation on an HP
Notebook?
