In addition to Alan:
After you have downloaded the zip file from the given link you have to open the zip file (zip folder). You can use CTRL+A and then CTRL+C to copy all files/folders in the zip file/folder. After that you have to got to Radarbox\Drivers folder and use CTRL+V to paste all the files from the zip file into that folder. After that you can install the drivers via device manager the way I stated earlier today. Windows is not capable to install drivers directly out of a zip file / zip folder.
That's not the shortest/smartest way to decompress a zip folder, but it may be the best way to make sure we get the drivers were they should be.
