RTL2832U/R820T chip/tuner receiver error

I have an RTL2832U/R820T chip/tuner combination receiver as recommended by FR24 and cannot get pass the driver installation. I have disabled windows driver auto install, run Zadig, chose the WinUSB 9v6.1.7600.16385 driver as instructed and all i get is "Driver install Failed" Any clues???

All executions were administrator run.
