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.

If you have Extension Manager installed, the application will launch and walk you through the installation process. If your computer returns an error, stating that it doesn't know what to do with the file, visit http://www.adobe.com/exchange/em_download/ to download the latest version of Extension Manager. Install Extension Manager, then retry installing the MXP file.
If Flash isn't one of the available options, quit Extension Manager. Launch Flash, and select "Manage Extensions" from the Help menu. Extension Manager should launch, recognize your installation of Flash, then allow you to install the extension.
When Extension Manager completes, you should see "SlideShowPro for Flash" listed in the Manager interface. You have successfully installed SlideShowPro for Flash, and may now quit Extension Manager.
