Okay, so I'm trying to install Jaguar for my dad, and when I insert the cd and double click the install icon, it does everything correct and tells me to restart the computer. So, it restarts, and everything seems fine at first, but the first screen takes forever. Then, instead of bringing me to the installer like it should, it brings up a blank gray screen, then a few seconds later it brings up a blue one, then a black screen with white letters that say "The Installer has quit due to an unexpected error (exit code 138). Please restart your computer." So, I did what it said, and the same thing kept happening again and again. I've tried everything. All the firmware updates are up to date, security updates and all that stuff is correct. I even read a document on the apple website that explained what to do in this case, and it basically told me to unplug all usb devices, which I did, it told me to try to install from OS 9, which I did, it told me to use startup disk instead of trying to install from the icon, which I did...I tried everything, and nothing is working. HELP!!!!!!!!!!!
