If you are planning to operate your CrossFire PRO machine using a Windows 7/8 computer, we have put together instructions for how to download and manually install the required USB driver for the CrossFirePRO Motion Control Card. These instructions have been added to the website and can be found here: http://www.langmuirsystems.com/firecontrol/guide#connect
So this driver installation is NOT NEEDED if you have a newer version of windows correct?
@bricklef correct. You will not need it for Windows 10
