I downloaded RealOne Player, but the installation failed because it said that my version of ActiveSync was incorrect. In order to get it working follow these steps: Start ActiveSync Double-click the RealPlayer installation file Get the error, but don't click 'Ok' on the error message Type %temp% in Run, i.e. Start->Run->Type '%temp' Open the folder named ~rnsetup Copy the realplayer.cab file in that folder onto the PDA In 'File Explorer' on the PDA double-click the .cab file to install. These steps were suggested on this forum . For a bit more information about installing .cab files read: http://pocketpccentral.net/help/tutorials/install_cab_file.htm
