Hi mpobs ,
I'm a little bit suprised because in my case Extractor waits for the game Pcars.exe and not Pcars64.exe ( into the waiting process window) .
The game isn't detected ( I'm not hear '´ game detected '´ ) but :
1- the game is well launched
2- when starting the driving session , Converter launched ( setup starting in program settings while detecting effect25) and the telemetry well launched from pcars and my sim rig runs fine.
The proof : http://youtu.be/ybMz1YqrEn0
Did you activated shared memory in the pcars option settings !
