As you have Apple QuickTime installed - perhaps you could uninstall Quicktime and try to run HyperNext Creator without it.
The files to remove for Quicktime are in the folder below:- (just in case QuickTime leaves them behind)
program filesQuickTimeQTSystem
Then try to run HyperNext Creator to see what happens.
It seems an earlier version of Quicktime had problems with shared libraries so causing apps dependent on it to crash as mentioned here:-
