Installing Plugins?

I’ve tried for awhile now to get Gen3 to work, and I’m beginning to think I’m placing the files in the wrong place, it comes with a folder named gt, my question is do I place the whole folder in the scripts section or do i take out those files and put them there? I also notice there are two folders in scripts, should I worry about those?

for windows
place the gen 3 script in .blender/scripts
place gt folder in .blender/scripts/bpymodules
make trees.
edit note> this works with blender 2.42a with python 2.4.3 installed
