How to change Alienware skin in ThemeMgr.exe via the command line?

I have my own icons and I wish to know the axact commands or the possiblility to switch the AlienWare theme by the command line. The key is to switch them from daylight bright skin to the dark night skin.

Any ideas how to achieve it?

There are suite files for temes in the Theme folder and bitmaps and icons at the folders named as the skin. The main program is ThemeMgr.exe.

When I launch *.suite file by the command line, the ThemMgr.exe open's up and it shows the right suite, but I wish the window should close automatically and be hidden after choosing the rigth suite, but not by the mouse - by the command line of course.

The key is, I wish to switch theme by the *.bat shortcuts: night and day
