Why use winrar you say? The self-extracting exe is using an API to have a look for previous versions - the setup packages for the actual software doesnt do this. Hence winrar works for my Audigy. Not sure about Live! but I dont see why not.
The driver pack that has AudioHQ and Playcenter - Use WinRAR on this!
