error occurred when installing classic os 9 with G4 panther ox ?

Hello:

I get an error that occurred when I try to install Classic OS 9 on a G4 computer with Panther installed that said, sorry a system error occured, "Installer Engine

error type 10 and 1. The installer OS 9 disc will freeze up when trying to install on my G4 computer. I would like to run both Classic OS 9 and OS X .

Also, QuickTime Pro is not showing up when QuickTime is open on the monitor. I have installed Final Cut Pro 4 and also QuickTime Pro with its serial number, but it seems that the QuickTime Pro is not showing up whe openning up QuickTime.
