I've just tried it and it works fine for me, too, although the outdoor example looks and feels horrible, don't expect much.
Make sure to check the following list:
* The following files should be installed:
* - "t7.dll" in the "acknex_plugins" folder.
* - "templates" folder in the GStudio7 root folder.
* - "t7" folder in the include folder.
* - "wdlv.dll" in GStudio7 root folder (if you want to use WED).
