I know how frustrating it can be when you lack the technical knowledge setting up scripts or whatnot. I had a very difficult time getting passed the last step just to find that it was a very easy fix to the problem, and I figured that someone might encounter the same issue so I'll be proactive and save you some time.
Basically I had do the 5 minute install and completed all the steps. Now in the installation instructions they say "just go to the domain and everything should install"(not in those exact words but you get the point).
I performed that task but once I typed in my domain name nothing loaded. I got nothing but a white screen and the page loading status at the bottom left hand of the browser read "done".
To make a long story short, instead of entering www.yourdomainname.com you can try entering
www.yourdomainname.info/202-config/install.php browser.
I entered that and everything worked fine from there.
Hopefully this will help someone
peace
