Close of autoitscript not working...

[Hyflex]

#NoTrayIcon
Run("game.exe start game", @ScriptDir, @SW_MINIMIZE)
WinWait("launcher.exe")
ProcessClose("launcher.exe")
WinClose("launcher.exe")
Exit

the launcher(script) is called launcher.exe

But i can't close it after it runs... You can see i tried all 3 ways of closing the script..

WINWait is waiting for a Window to appear with the title launcher.exe, unless the launcher script is popping up a window with that title, the script is going to wait for that before continuing on. If there is a window you are looking to close then use the title of the window, otherwise you could use processwait for launcher.exe
