It may be saying something about the "volume" not being found. What it means is that you have to name the volume, the SD card, "VW_SOUNDSYS" before it will put the files on your card. Remember, it's not just unzipping files; it's creating a bootable image. So, the name of the volume is critical for the EXE file to work. If your problem is something else, perhaps reformatting the card will help. But that's a guess, to be honest.
