I have over 100GB of free space on my hard drive, so that's not the issue.

iLife '08 requires a Mac with an Intel, PowerPC G5, or PowerPC G4 processor running Mac OS X 10.4.9 or later and QuickTime 7.2 or later. Some other special system requirements [2] apply as well: iMovie '08 requires an Intel processor, a Power Mac G5 (dual 2.0 GHz or faster), or an iMac G5 at 1.9 GHz or faster; iMovie no longer supports PowerPC G4-based Macs. Also, iDVD requires a 733 MHz or faster processor.
