I've not had any success attempting to install a USB driver for the KFLOP on Windows 10.
1. Opened Device Manager
2. Right-click KFLOP - Motion Controller
3. Choose "Update Driver Software"
4. Tell Windows to look for drivers in the "USB Driver" folder, inside the KMotion432 release folder.
5. Get an error message:
Windows encountered a problem installing the driver software for your device
KFLOP - Motion Controller 4.XX
