After an install, we still have to add various folders for avatars, etc etc, and have to delete the installation file.
Maybe I am spoiled after using SMF for a number of forums, but they have a turnkey installation, and delete the install upon completion.
SO many people have had problems over the default for the HTTP referrer, why not just have it off, which seems to be needed by most people...
It is so frustration for a new user/installed to have to figure out how to complete this so it works...
The key is TURNKEY installation...
Just my thoughts..
