I'm trying to install iMovie HD 6 on my new iMac (which came with iLife'09 pre-installed). This old version of iMovie - IMO - still holds some features that are absent in the new iMovie... but when I tried to install it, it gave me this message... Anyone else with this issue? is there a way around this? (I don't have my old iMac which had iLife'08) Thanks!
