In the case of win7, press F8 to enter debugging mode when booting, and there is one option, usually the last one, which is to disable the forced signature of the driver. Select him and you will enter the system and install it. This ban is only valid this time. I want to install a similar driver in the future, and I have to do so.

Win8 is a little troublesome. In the lower right corner-Settings-Change Settings-General-Advanced Start-Debugging-Disable Driving City Mandatory Signature. Then install.
