I created a tutorial a while back, that showed how to set up your computer so you can just double click the .umod fiels (Unreal Modules), so that they will start the set up process.
Here is the link:

I had it on a site I was working on a while back
http://www.2399clan.net/skillz/skins/new/
However, I ran out of alot of free time and never completed it. I don't think I am now anyway, but it will still be archived there.
Later I will see about converting it so that it will display on the forum, but until then just click the link.
