using 296.10 NVIDIA drivers. Modified from Laptopvideo2go.com, no work

I had these exact drivers working on win 7. They wont work on windows 8. It passes the checking system compatibility but fails during installation. While it installs the screen flashes black and then it says, "NVIDIA Installer failed".

I have windows 8 64bit

Hi,

You need to do one of the following:

1) Sign the driver.

2) Disable driver signing enforcement checks permanently.

3) Disable driver signing enforcement checks each time at boot from the menu.
