I HAVE searched, and tried all solutions that were given for this in previous threads, so don't flame me! I have a similar problem to all the other threads like this. My Installer app can't install anything. It used to say "Package Download Failed" (with no explanation why at the end) but now it says "Main Script Execution Failed". I have tried: Reinstalling Installer Reinstalling Community Sources Manually checking all sources for typos Changing Installer permissions Clearing Installer queues (several times) Rebooting iPod (several times) Checking WiFi connectivity Fix NVRAM via ZiPhone (this appears to have helped some people but my ZiPhone didn't have the option to do it) Also tried HTML: cd / cd Applications/ chmod +s Installer.app/Installer chown -R root:wheel Installer.app I'm running a jailbroken ZiPhone 1.1.4 iPod touch. As you can see I've looked at all the other threads, but they haven't solved my problem. Help?
