Problem with QT Player

[David C.]

Hey folks,
I have a very simple application in which one aspect of the app uses
the QT player, always pointing to the same named MP3 file on my
server.

Yesterday, I went to visit a friend and gave him  a copy of the app to
try out and every aspect of the application worked as intended except
for the QT player. Where the controls would normally be located, there
was nothing but a white empty space instead. Just to be sure there
wasn't a problem with his QuickTime installation, I had him download
and install the latest copy, yet we got the sames results.

I tried the same application on my laptop (positioned right beside his
and NOT being the machine I developed the application on) and it works
flawlessly.

The app was built on a Win 7 machine running LC 4.51, my friend's
laptop is a Win 7 machine and the laptop I used to run the test beside
his is a Win Vista machine. This is the first time I've used the
Player control so I'm stumped.

Is there some sort of QT external required or do you have any ideas
what might be happening?
