WINDOWS  7, 8, 10

  1. Download Zadig tool: http://zadig.akeo.ie/
  2. Start up the KISS FC in bootloader mode (close the boot jumper oder keep the boot button pressed) and connect to your computer (you should hear the usual chime).
  3. Run Zadig (it doesn’t need installation). It should look something like this (but the button will probably read “Install Driver” if you haven’t done this before). Note: If the STM32 BOOTLOADER isn´t listed, go to “Options” and select “List all devices“:zadig-tool-windows
  4. Select the WinUSB driver (the other choices might work, needs testing), and hit the Install button. The process should only take a second and result in a success message. In Windows Device Manager, the KISS FC should show up like this:
    AQM4-bootloader-win-device-manager
  5. You should now be able to flash the KISS FC through the Chrome App GUI v1.0.12
