Unfortunately, AirServer will not run on Windows XP or Windows RT. There are no older builds that would be supported on Windows XP.

This is because AirServer uses Windows port completion for high performance networking, which is only available on machines running Windows Vista or newer. This delivers considerably better performance when mirroring.
