What version Flash player has to be downloaded to play .swf files on Windows mobile 6.5? [closed]

I'm trying to view websites with Flash content in Internet Explorer on a Windows Mobile 6.5 device [HTC touch HD2]. It says it has not got the right Flash player. I tried to install the player but the device is giving me an error. It's saying the installer is not a valid Pocket PC application.
