SIM just keeps creating zip files

I'm new to the Altiris/Symantec product line.  I downloaded what I thought was a trial version of Altiris Client Management Suite - turns out it's a downloader for every package under the sun.  So I select Client Management Suite and this thing creates a zip file.  No install, no indication as to how to install.  Open the zip file and it starts the same installer all over again - which just wants to create yet another zip file.

Any help getting a trial version of the client mgmt installed or should I just stick with SCCM?
