Clean install 2.4 stalls

Hi, I am a novice trying to install Moodle 2.4 on a hosting service with CPanel. Server meets requirements: PHP 5.3.23 MySQL 5.1.68-cll
linux (2.6.32-279.22.1.el6.x86_64)

I have set up directories, database&user, unpacked files per instructions.

Setup checks all show OK (green). Stops on next screen and shows only:

Installation
           System

Any orientation is appreciated. I am willing to research but I just don't know where to start looking. Thanks.
