Right, it does get installed somewhere, at the very
least in /Quicktime/QTSystem. But, at installation
time, the user could choose any possible installation
path, C:\Program Files\Quicktime, C:\Quicktime,
C:\Something Else\Quicktime, etc...
So, how is my application supposed to find it? There
is no comparable, PATH-TO-QUICKTIME ENV var.
The QTJava ENV var is being set if there is a
pre-existing Java installation, but what if there
isn't? Ideally, the QTJAVA ENV var should be set to
/Quicktime/QTSystem/QTJava.zip by the QT installer
itself.
The only hope is that if there isn't a current Java
install, the QT installer is smart enough to still set
QTJava to /Quicktime/QTSystem/QTJava.zip, but I'm not
optimistic.
This is not that simple an issue.
Appreciate your feedback.
