Issues installing on a Mac

Hi there, I'm trying to install the Toolkits on a Mac... I'm new to Xerte so hopefully I'll makes sense! I thought it would be easier to screen capture on a video... here is my problem: You tube clip . Thanks in advance. I'm going away from internet access for the weekend and wanted to have this on my laptop so I can have a play! Any advice would be much appreciated.

Around 1:14 you show a listing of the setup folder. That is INCOMPLETE.

It looks like you installed an update package, and not the full zip! Please use the full installation zip.
