DL it to your desktop... LMAO. Then you need to extract the installer and uninstall ANY old audio codecs or drivers u have right now and reinstall it using the direct installer. It is a .ZIP file or .RAR file. U need to extract it, and then install it. Placing the files in the folder does nothing, this isnt Linux we are dealing with, Windows has its icky little registry to deal with, which also has to be updated (the installer will do that for u)
