Creating DMG file for Sims 3 Pets

I tried making a DMG image out of the entire folder (from the unRARed G4TW version of the Pets torrent), but it still says it cannot verify the integrity of the installer. Can anyone help me out? I've been trying to get this game to work for days now.

From what I've read you have to be careful to unrar your download using only Stuffit Expander, did you do it that way?

Not only that, you need to use the certain version that is specified
