Michael, the drivers come in a zipped file and need to be extracted to somewhere you can remember like the desktop.
Once you have done that go to the start button/Devices and printers and you will see the Radarbox usually under unspecified. Click on it, when the window opens up click on the hardware tab. You will see a button marked Change Settings, press it. On the window that opens press the Drivers tab.
Then on Update Driver on the window that opens up. You will then be given 2 options, press Browse My Computer For Driver Software. A new window opens up. Use the browse button to search for the folder you extracted your drivers to, when you find the folder press next and the drivers should install and you can start the RB software.
