I've downloaded the executable for the demo (X-Plane 11 Installer.exe), but get this error message:"The version of this file is not compatible with the version of Window you're running." I'm running Windows 7 Home Premium on a 32-bit operation system.
I've attached the log file which, interestingly enough, has "Windows 6.1" listed, which is incorrect.
