I don't know what you downloaded. The official download page can be found at http://www.conitec.net/english/gstudio/download.php. The demo contains the script editor SED, the world editor WED and the model editor MED.

What do you mean with aamd patch file thing?

If you got no WED your installation seems to be damaged.
