Two error messages while trying to install Ustream Producer

Hello friends,
I desperately want to install Ustream Producer, but these two messages appear.

Ustream Producer.exe – System Error
The program cant start because QTCF.dII is missing from your computer. Try reinstalling the program to fix this problem.
OK

Ustream Producer
Ustream Producer was unable to start
Unable to find the QuickTime plug-in. Please
reinstall Ustream Producer
I have QuickTime installed, and this is a new version of windows. So, I don’t know why this is happening.
Please advise me.
Thank you all.
