You should extract the files to somewhere you can remember such as a folder on the desktop, call it RB 64bit drivers. Then go to Start/Devices and Printers/Unspecified/Radarbox right click Properties/Hardware/Properties/Change Settings/Driver/Update Driver/Browse my Computer for Driver Software/ use Browse to direct to the folder you unzipped the drivers too and then Next and the drivers will install. Turn on RB and all should be well.
