I have had iLife installed on two machines once already.... I am in the middle of rebuilding a lab before the students get back. I reformatted the drives and installed the apps. but iLife continues to come back with strange errors. The first one is that I have to use the DVD disc because I have a DVD drive, though it is only a combo drive. On the other hand and use the DVD, then I get the error that one of the four or five programs is running... not true... checked TOP and other places just to make sure. I corrected permissions and deleted old reciept files... just trying anything.. no luck.. anyone have any thoughts... I am reformatting one drive again just to try that approach too.
