I am sending several avi files edited in Premiere Pro cs6 to a theater group using dropbox. I have sent out to over eighty members these files and I have one member that cannot open the file from the entire group. When I asked her to forward the email back to me, I received the dropbox file with no where to click and open it. Unfortunately, she doesn't seem to understand when I question her about what system she is using, etc. because she doesn't reply to my questions. Any suggestions as to what I can do to try to get her to receive these files? Thank you.\
I wonder if she is on a Mac? I don't believe Macs can play .avi files. Beyond that, I would question the use of an .avi file in the first place for delivery - is there a specific need for the format to be .avi ? For electronic delivery, .mp4 is the usually the best choice because the files are much smaller than .avi and an .mp4 should be universally playable on PC, Mac, tablet, etc.
