Question: Why is it not possible to stop a running game with Windows 'TerminateProcess'?

Development Platform & Builds

In my system, I have an application controlling starting and stopping my programs. This application will try different ways (platform dependent) to stop a started application. As last try, it uses TerminateProcess on Windows. Unfortunately this does not work, the game will not exit.

The game is build for shipping with RunUAT.bat using arguments -nop4 -utf8output -platform=Win64 -clientconfig=Shipping -serverconfig=Shipping -build -cook -stage -CrashReporter -noiterate -archive

If it is not possible to use TerminateProcess, is there another way to stop a running game application from an external program?

Ok. I have some more information. The executable that is created in the archive directory on build is actually starting another executable located in Binaries/Win64 which is the actual game executable. If I use that executable directly by my controlling application, it will start and stop perfectly.

Is that also a valid way to start the game?
What is the purpose of the executable that starts the actual game?
