Manuel,
Exactly the same as myself. Download the drivers
http://www.airnavsystems.com/Download/ANRB/Drivers/ANRB-Drivers-20161222.zip then as they are zipped they will need to be extracted to somewhere on your computer, I would suggest hat you extract it to the drivers folder on Airnav Systems/Radarbox. Once done you will see a new folder inside the drivers folder named ANRB-Drivers-20161222.
Go to Devices and Printers/Unspecified and you will see your Radarbox. Right click on it, then click on Properties. Hardware tab/Properties. Change Settings, Driver Tab, Update driver, Browse my computer for driver software, Click Browse and click on the driver folder and you will see ANRB-Drivers-20161222, click on it and then OK and the drivers will install. Start up Radarbox and all should be OK
