Have the same issue. Win7 64-bit. Had the utility installed for one day, barely had the device configured. Moved my USB keyboard to the Kodi box (to test Ctrl+F12 suspend) and then re-attached it to a different USB port. That triggered Windows keyboard driver installation process and I guess messed up something in the USB driver chain. Tried re-installing, removing the driver and re-installing, different compatibility options and tried the ZADIG utility.
