OK, I downloaded and extracted. One extracted into a directory called "Installation" and the other into a directory called "Installation 2". I assume they both were to be uploaded to the "installation" folder on the extracted archive. Then I launched the wabonline.org/installation/index.php script and it looked like it was going to work but after the initial confirmation screen I got the following:
Application Error
