I just finished downloading the program, and pressed "run the program". A message came up saying "can't fine graphic interface file, you must have moved it", but i didn't touch any files, this is the full version, not the demo.
If you cannot launch the X-Plane 11 beta, please file a bug report. Include the full log.txt after quitting X-Plane.
