Normally you can just continue
It's just MS not being aware of this new driver
There's a Driver Signing button in the HardWare Tab of your System properties
What?
Ok Just go to Start->Run-> sysdm.cpl
Then click on Hardware Tab
Then click on Driver Signing button
And you can select "ignore", and make it the default action
Apply Ok Ok
It only gives me the 'Ok' option, I turned it to ignore and tried again, still gave me that error, I made sure I was using the one for my chipset, and double checked, it's the right one.
