If you're using Mac OS X 10.3.x or above, then you will not need Stuffit Expander. You can do this by using the WinZip application on your PC running Windows XP, or by using Stuffit Expander on your Macintosh (needed for OS 10.2.x or below). NOTE: This file is a compressed zip file that requires 'unzipping' after you download. This is the player application for Vima Tunes.
