iExplorer does required QuickTime

I need to backup some stuff from iExplorer (used to be called iPhone Explorer), so I installed it, ran it and found that it was not working.  After spending half an hour to diagnose, I eventually found out the reason: installing iTune doesn't automatically install QuickTime, and QuickTime was not on my machine.  So I went and download QuickTime, and I could successfully launch iExplorer then.
