There was a version of blender somebody had made that was portable and had all the tools needed. Let me see if i can find it edit: dang. Cant find it :/
you have to have a really vintage blender portable with the addon preinstalled i still proably have it somehwere and some people might, it was on ror forums but with those its probably gone now. ask around.
