Like QT 2.1.2, which is still present on many win98 machines, and you need at least
version 4.x to be able to play e.g MP3 files and at least v. 5 or above to play MPG videos

But on windowze apps, i want to check the qtversion BEFORE i decide to use or not use QT...
See one of my last mails concerning media files that are playable inside of player objects without QT...
So i want to check if there is an "up to date" version of QT on the target PC before i decide
to "set the dontuseqt" to whatever...
But with the current behaviour this is simply not possible, since once QT is loaded, you
canot get rid of it as long as your rev-app is running...
So this is a bit like a paradoxon:
I can check, but then the result is useless, since i cannot change anything if it is
not what i need...
Know what i mean?
Therefore my question: Is there a registry entry that we can check instead?
Note - I am totally naive about Windows registry, and how you access it, but.... I see an entry for
HKEY_LOCAL_MACHINE / SOFTWARE / Apple Computer, Inc. / ActiveX / QTVersion
that looks a possible candidate. I can't see anything else in the QT hierarchy that looks like a version number. (And in fact the QT player on Windows is perhaps the only program I've seen that doesn't give version info in its "Help / About ..." menu screen).
Does seem like there should be a more direct way ...
