Adobe has discontinued flash player 64 bits for linux, as said in Adobe official announcement :
"We have temporarily closed the Labs program of Flash Player 10 for 64-bit Linux, as we are making significant architectural changes to the 64-bit Linux Flash Player and additional security enhancements. We are fully committed to bringing native 64-bit Flash Player for the desktop by providing native support for Windows, Macintosh, and Linux 64-bit platforms in an upcoming major release of Flash Player. We intend to provide more regular update information on our progress as we continue our work on 64-bit versions of Flash Player. Thank you for your continued help and support. Stay tuned to the Flash Player discussion forum for further announcements."
