If after installing my driver with hybrid graphics option in Vista/Win7 x64
you have an error that the Nvidia driver cannot be enabled try the workaround found in this guide:

It seems the .sys files has to be "signed" to be enabled for your system.
This is not a driver bug but a vista/win7 x64 way of ensuring that the drivers are vista/win7 x64 compatible on your hybrid systems.
The drivers require a digital signiture before they can be loaded on boot. If there is no signiture then the Nvidia gpu will fail to initialise.
You can thank microsoft for this.

Do not worry though. After you have installed the drivers in the normal way follow these workarounds:

Work Around 1

-Reboot system
-On boot go into advanced boot options by tapping F8 repeatedly
-Choose disable driver signiture enforement
-The drivers should now work as it should

In this method you have to keep doing this after every reboot. But this is a good way to see whether the drivers will work on your system without much effort.

Work Around 2

MAKE SURE YOU TURN UAC OFF BEFORE DOING THIS!

-Download Driver Signiture Enforcement Overidder
-Run the program
-Select "EnableTest Mode" and follow on screen instructions
-Reboot your system and you will see test mode on the four corners of your desktop
-Open the program again and click "Sign a System File"
-Browse to these:
C:\Windows\System32\drivers\nvlddmkm.sys
C:\Windows\System32\drivers\igdkmd64.sys

you'll need to sign both of them

-Select "Exit" and reboot
-Drivers should now work as it should.

To remove the watermark use This for windows 7
Make sure you select program to run as admin, press R and reboot.

With this workaround you dont need to keep pressing F8 each time to disable the microsoft driver enforcement.

Work Around 2

Download: Read Driver Plus
Install
It does workaround 1 for you automatically but may not work on all systems.
Use at own risk.
This is the simplest method.

for s42 users that have problem installing Dox's driver in Win7 x64, this is how you should install the driver(works for me)

1)run the dox driver just to extract the driver files first
2)go to device manager, make sure the intel card is installed(i think by default it will be installed by windows 7)
3)if so, on the "standard VGA adapter", right click and select "update driver version"
4)select "Browse my computer for driver software"
5)after u select it, u will see that it wants you to locate a folder to scan, ignore that, instead, click on the "Let me pick from a list of 6evice driver from my computer"
7)after selecting that one, you will only see "standard VGA adapter" on the list, it's normal..now, select "Have disk"
8)it will ask you to locate the driver, just select the folder that you extracted Dox's driver, then it will show the inf file, select the file and click ok
9)now, you will see nVidia 9600M GT on the list, click ok and it will install the driver
10)after it is installed, DO NOT RESTART FIRST...remember to select power mode to power saver
11)restart and boot with disable force driver signature*, and have fun


*the methods are stated in the original install guide from Dox here:

use method 1 to test if u succeeded installed the driver, and if yes, then use method 2 to sign the driver files
