Today I decided to reinstall Safari on my family's computer, since it's been hiccping lately. I deleted Safari and everything it was attached to, and used IE to download the latest version of Safari from Apple.com. When I ran the Installer program after downloading, it said that I can't install Safari because "The system cannot use this software" and that "You cannot install the software on this volume." I am running OS 10.3.2. Help!
