By default, Windows 7 automatically blocks users from installing unsigned drivers to the system. Although intended to be an added security feature, this setting makes devices or peripherals that you'd like to connect to your computer completely useless.
In order to proceed with the installation of an unsigned driver, you must first disable a driver's signature verification. This article will teach you how.

Before beginning, please note that we recommended that you enable the signature verification of drivers. Please proceed at your own risk.
Go to Start > Run, and type
bcdedit /set nointegritychecks ON
. If the Run command is unavailable in the Start menu, please refer to this FAQ.
Now, restart your PC and try to install the unsigned driver. To do this, head to Start > Run and type
bcdedit /set nointegritychecks OFF
Restart your PC. The driver should be properly installed upon reboot.
