Need to determine if Quicktime is installed

[Stuart Wells]

I am doing a very simple program for a friend that gives you some choices when you insert his CD. The cd requires the user to have quicktime 4 or later installed on their system to work. The way we did this before was just ask the user but I want to change it for future releases so it knows if quicktime has been installed. Can anyone help me, I have searched everywhere for a way to do this without looking at the default directory that quicktime installs to.

If you check the registry in
'HKEY_LOCAL_MACHINE\Software\Apple Computer, Inc.\QuickTime\'
There's a key called 'InstallDir' with the installation Directory as the value...

You could retrieve this setting using the RegEnumKey API call and check for the file using Dir$

There's probably a better way to do it though.
Could you try Shelling a .mov file and seeing if it returns an error?
