Note Digitally Signed USB Drivers for KFLOP are now available here

This eliminates the need to disable Signed Driver Enforcement to load the Drivers as described below.

Because the driver for the KFlop board is not signed, the computer must be put into “test mode” in Windows 10 to enable installation.

This is accomplished through the following steps:

Click the “Start” button
Click “Settings”
Click “Update & Security”
Click “Recovery”
Click the “Restart now” button under “Advanced startup”
Click “Troubleshoot”
Click “Advanced Options”
Click “UEFI Firmware Settings”
Click “Restart”
Follow your PC or motherboard vendor's instructions for disabling "Secure Boot" on your particular machine
Click the “Start” button
Type “cmd”
Right-click the “Command Prompt” listed in the “Start Menu” and choose “Run as Administrator”
Click the “Yes” button
Type “bcdedit.exe –set loadoptions DDISABLE_INTEGRITY_CHECKS” without quotes (note: there are two ‘D’s in ‘DDISABLE’
Press the “Enter” key – you should see “The operation completed successfully.”
Type “bcdedit.exe –set TESTSIGNING ON” without the quotes
Press the “Enter” key – you should see “The operation completed successfully.”
Reboot the computer
This has succeeded if the screen says “Test Mode” in the bottom right corner

Setup Driver for KFlop Board

Make sure that the controller is powered on and that the USB cable is connected between the computer and the controller.

Click the “Start” button and type “Device Manager”
Press the “Enter” key
Under “Other Devices”, right-click “KFLOP – Motion Controller” and choose “Update Driver Software…”
Click the “Browse my computer for driver software” button
Use the “Browse…” button to select the folder that KMotion was installed in (i.e. “C:\KMotion433q”)
Click the “Next” button
On the “Windows Security” screen, click the “Install this driver software anyway” button
The screen should end with “Windows has successfully updated your driver software”
