I just download 'n installed Blender 2.69 for Win 64 for my system with Win7/64. Then I try to make a simple game just to test the engine. But when I export it using Save As Game Engine Runtime, I get this error report.
I just follow the link given above ( http://developer.blender.org/T37157 ), download the py script then replace the old one with the new one, and its work!!
