Adobe Flash Player 9 recognizes K-Meleon and installs correctly.
The URL http://www.adobe.com/downloads/ provides links to the Flash and Shockwave plugins. If you have to choose, choose the file for Netscape/Mozilla/Opera/CompuServe. When prompted to Save As, save the install_flash_player.exe onto your computer.
Close K-Meleon and go to the location where you saved the file. Double-click the file to start the Install process. Follow the instructions on the setup screens. The installer will copy the Flash Player files to your computer.
You can check to see if this plugin is installed by choosing Tools - About Plugins or typing about:plugins in the K-Meleon URL bar. If you find Shockwave Flash listed, K-Meleon properly recognizes your Flash installation.
