Well, since different people have a different styleid as their root, I didn't want to just pick a number out of the blue. I'll probably modify it so the user can select with a dropdown which one they want to install to in a future release. But at the same time I tried to make the whole install of the hack as automated as possible for people who don't know much about how vB works.
Also, it is my first time coding an installer, it's either that or a massive txt file with all the stuff to do...
