Install Fails & Incompatibility

[aleshu]

Hi, I tried installing the latest beta and non-beta drivers in 2 different machines and I am getting this screen after rebooting (same result in both machines, one laptop and one desktop). The result, the display icon does not show up in the tray bar.
When I try to search for a Display driver, it ends up with the 'Cannot install this hardware' screen. What is it looking for or where is this driver??

BTW, all my video drivers are latest versions and from original vendors.

Any help greatly appreciated..

PS: here's the install log
