I'm experiencing the "Main Script Execution Failed!" error anytime I try to install apps. I've updated Installer.app to v3.0b10 but the problem persists. Based on reading various posts I suspect the problem is that I need to reinstall the BSD System. But I can't do it through Installer because I get the "Main Script" error. Is there another way to install the BSD system? I've been searching but have only found references to using Installer. Anyone know where I can download it?
