When trying to play a Quicktime files recently I got a window saying,
'Old Quicktime Please upgrade to Quicktime 7.0 or later'.
So I went on Apple's website and downloaded Quicktime 7.0. However when I get to the 'select a destination' window on the installer I keep getting a message saying,
'This disk is dimmed because there is a newer version of quicktime already present'
and then I can't proceed. I've tried to trash all traces of my current Quicktime package but no luck.
