Technological Requirements
The LAUNCHcast music player (from development date to February 2009) required Microsoft's Windows Media Player 9.0 or higher to function, although it could not be streamed from the Windows Media Player itself. Before the merger with CBS Radio, LAUNCHcast only worked with Microsoft's Internet Explorer 6.0 and up web browser with Flash 6.0 or higher, and in Yahoo!'s Messenger and Music Engine programs on the Microsoft Windows operating system 98, ME, 2000 Professional, XP (Home and Professional). LAUNCHcast did not load properly using a Firefox web browser. According to Yahoo!, the LAUNCHcast music player was not compatible with the Mac OS X or Linux operating systems, however as of February 16, 2009; this may not be the case. Yahoo! stated that following CBS's acquisition, loading the player in Firefox may become possible.
Since the relaunch of LAUNCHcast by CBS, users were only required to download the latest Flash Player plug-in (currently Version 10). See external links (below) for Yahoo's help page on system requirements. The requirement still stands with the Yahoo!/iHeartRadio merger.
