USBSerial driver on Windows 8

I have a KL25Z program that uses the USBSerial connector. I can't install the serial.inf driver under Windows 8.1. It complains that "third-party INF does not contain digital signature information." Is there a solution to this problem? It works fine under Vista.

Thanks, Tom

I found the procedure for disabling Windows 8 signature enforcement at: https://learn.sparkfun.com/tutorials/disabling-driver-signature-on-windows-8
