X-Plane 11 Installer (the demo) crashes immediately on launch. Blank black window with title "X-System", and a system dialog that says "X-Plane 11 Installer.exe has stopped working."
This is a 3GHz Core i5 system running Windows 8.1 (64 bit).
I see some system information in the installer log file, but nothing that clearly indicates a problem. It shows OpenGL Version : 4.2.0 - Build 10.18.10.3262.
Thanks!
