You'll need to use the pre-defined width and height of the GUI with the internal variables A_ScreenWidth and A_ScreenHeight and force Param2 of Gui, Show as an expression to make it work. For example if the width of the GUI is 900 and the height is 550:

Gui, Show, % "x" A_ScreenWidth - 900 " y" A_ScreenHeight - 550 " w" 900 " h" 550, The GUI
