SlideShowPro for Flash is an ActionScript 2 and ActionScript 3 component for Macromedia Flash MX 2004, Macromedia Flash 8, and Adobe Flash CS3/CS4. It is bundled as a Macromedia/Adobe extension file (MXP) and installed through the standalone Extension Manager application.

To install SlideShowPro for Flash, quit Flash (if it is currently running). Double-click on the ZIP you downloaded from your Account Center profile page, then open the folder the ZIP creates. Inside will be a folder named "Extensions." There will be two .mxp files inside, one with "AS2" and one with "AS3" in the file name.

If you are installing the extension to use with Macromedia Flash MX 2004 or Flash 8, double-click on the "AS2" version to begin installation. If Adobe Flash CS3/CS4, you can install either the "AS2" or "AS3" version, or both. Unless you plan on publishing SWFs that are older than Flash Player 9, you can install just the "AS3" version.

Note: If your ZIP won't open, first make sure you've downloaded the ZIP directly through your browser and not with a third party download manager. Download manager apps interfere with the authentication process. Second, try using the ZIP utility built into your operating system instead of a third party ZIP client. Your ZIP should open fine in Mac OS X, Windows XP/Vista.
