Till the latest release of Adobe Flash Player, there wasn’t support for 64-bit either in browser or at system level. With this release Adobe has made it support native 64-bit. Thus, Flash Player can now take advantage of native support for 64-bit operating systems and 64-bit web browsers on Linux®, Mac OS, and Windows®. This is a great advancement for Flash player to deliver more on 64bit platforms.
You can download the Flash player here: http://get.adobe.com/flashplayer/
Note:The 64-bit Flash Player installer includes both a 32-bit and 64-bit version of Flash Player.
