OK.. and Hmmm....
Please confirm: You rebooted and then displayed the registry data? You did NOT start the nVidia install yet, right?
I ask cause:
The registry data I asked you dump is where MS installer saves Setup installation info. I wonder if you might
> Have a wizard running OR
> Have old Setup data in your registry (e.g. from a corrupt prior installation attempt or if you recall if you had a BSOD in the middle of a prior installation??).
1. What does Windows do if you click YES to minimize nVidia? Do you see any other installer windows?
2. On reboot, try
Control Panel->Add Hardware. Do actually see the new hardware wizard open up? If yes, try using it.
> Allow it to connect to Windows Update this time only
> Install the software automatically
and.. btw... I see two of three InProgress flags set to TRUE in your data
SystemSetupInProgress REG_DWORD 0x0
FactoryPreInstallInProgress REG_DWORD 0x1
AuditInProgress REG_DWORD 0x1
Though i'm not yet sure just what that might mean..but will look further.. if you could also try the add'l steps above in the meantime...
