Prepar3D executes back to Desktop

[Lox]

Hello, :D



After Win 7 64 bit update, Prepar3D.exe exits back to desktop with no failure or error code.

I re-install Prepar3D from scratch according to their description but, still the same problem.



Also when I tried to run LearningCenter I get the following error...C:\Windows\Microsoft.NET\Framework64\v4.0.30319\mscoreei.dll could not be loaded. The file is there... Why can it not be loaded?



I re-installed all the proper libraries, etc, etc but still no help!



Any idea???
