I keep trying to play Quick Time movie and get an error message, why wont it play?
AVI is not a supported format.
Because it is a stolen version of the original.
Contact the Vendor, see if you can get a replacement or refund.
It's a stolen product and no replacement can be offered.
I know , (so that's the only advice that I would give the OP)
Quicktime doesn't support .avi files. Download VLC media player and use it to play .avi files.
