So I let my brother use my Powerbook G4 with OSX 10.4 this past Christmas. He being the nice kid he is decided to clean out all the spyware in my computer, trouble is there was no spyware, and he wound up deleting Disk Utility and Installer thinking the programs were spyware. So now I go to install iLife '08 today and I can't open it with Installer because it's been trashed! So I went to try and restore with my Install CD and it's scratched and isn't recognized! What can I do? I don't feel like dishing out $100+ bucks for Leopard, and I know my brother can't afford it. Is there any way I can recover these programs without an Install disc? Of course my Apple Care ended a couple months ago.
