New video driver install fails because of possible bad registry ke

I tried to load new NVIDIA drivers on my machine and keep failing during the

install. This happens no matter what version video driver I try to install. I

even used Driver Cleaner Pro to ry and make sure all NVIDIA driver data was

removed from my system. So I opened up regedit.exe and started searching for

and deleteding all occurences of the phrase NVIDIA. When I got to a specific

key, thie key would not delete. I could not open the key or change the key'e

permissions. This key was HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation.

What can I do to remove this key? I think this is what is causing my

install to fail.
