Unzip the files to (yourname) folder. Use start/settings/control panel/add new hardware, to select your audio device. You can use the "have disk" button and point to "yourname" folder instead of a disk. Alternatively in the device manager select "sound/video/games controller then select each device in turn - click on "properties" then "driver" and then "update driver" button. Click on "search for better driver..." then "next" then tick the "specify location" button and enter the path to the folder containing your driver - eg c \downloads\yourname and click "next".
