After reading Ingo's response that his works with 1703 I checked a couple other things.
First I uninstalled the RB via Device Manager and then using Add/Remove Programs and then deleted ALL AirNav application and files that I could find on the computer, then searched the Registry for any AirNav entries and deleted them. I then unplugged all other USB devices (2 SDR's, 14 USB-serial cables for radio receivers and the hubs that support them).
I then plugged the RadarBox back in. Windows installed drivers automatically and reported them as the best ones. I then downloaded and installed the RadarBox 6.01.001 application, installed it and tried it again. Still got the same results, the splash screen identified RB1 but the application reported the same No Hardware message and red box.
I then force-wrote the drivers from the AirNav downloads site and tried it again, still no joy.
I then unplugged the RB and plugged in an SDR, the SDR worked fine.
I can't understand the issue here if Ingo's install works and mine doesn't with the same version of Windows.
Ingo: What version of the RB application are you running? Could it be the application that is broken and not the drivers?
