I have following problem.
All my FSDT airports works fine.
Installing airports and GSX works also fine
Installing airports and XPOI no problem.
But when i install GSX AND XPOI together, Windows 8 tell me, that P3D was closed, coutal.exe was crashed.
Open AL fix was installed. All rights set. UAC out. All Versions from 03-23-13
Thanks for help.
