Luckily, I figured out how to turn off these driver verification checks.
In order to do this, you must enter the following commands in command prompt (run as administrator)
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS bcdedit -set TESTSIGNING ON
Please keep in mind that this MAKES YOU VULNERABLE to malicious drivers, packages, blah, blah, blah.
Once you've installed the drivers you've been having trouble with, you can turn it off with these commands using the same process.
bcdedit -set loadoptions ENABLE_INTEGRITY_CHECKS bcdedit -set TESTSIGNING OFF
This should also work with Nexus 7
For those who don't even have the drivers, they are here: http://www.mediafire...hopj725o3dahinu
Once you have done the above method:
-Boot GNex/Nexus 7 into fastboot mode and plug into your PC
-Open Device Manager
-You should see "Android 1.0" as a unknown device. Right click, hit update driver
-Browse for the directory that you extracted
-Complete the prompts
