I have an Asus X502CA Laptop with windows 8.1(64 bit)It has the standard 10.18.10.3308 driver installed for my Intel HD Graphics 4000. I downloaded the new 10.18.10.3316 driver, but when I try to install it I get the message "The driver being installed is not validated for this computer. Please obtain the appropriate driver from the computer manufacturer."
The latest video drivers for your controller is version 3345, you may want to force the installation of the driver manually.
