@josh: should be able to install 185.85 then...i wonder what is the issue in the installation...hmm...
did u switch to power saving mode after installation then reboot? that is needed to make the driver work for the first time...

what workaround do u mean?
disable driver signature enforcement? that one is a must for DoX's driver to work on x64 environment

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.
