Sims 3 Supernatural Installer app closes immediately

I downloaded the torrent for the Sims 3 Supernatural and extracted the .rar to my desktop. When I tried to run "The SIMS(tm) 3 Supernatural Install.app" the application blinks on my dock, then disappears. I'm running OS X 10.8.2 on a mid-2011 iMac.

uTorrent reports that 14.1MB were wasted. Could that be the issue? And if so, can someone supply me a link to where I can download the installer.app, or to an uncompressed torrent so that I could download only the installer?

You have to extract the .rar file using Stuffit Expander.
