Ok you just have to Move both the files:
_AEAF660D.exe
AEAF660D.exe
Place them in the Anim where you installed the game and Click the _AEAF660D.exe to start the game.
You can either make a shortcut for the file or just change the Shortcut on the desktop by right clicking it and in the target location replace musuko2.exe with _AEAF660D.exe.
