I'm trying to make a windows-only screensaver. My client is not willing to install quicktime, so I made an AVI movie (with Cinepack codec). I unchecked the quicktime and opengl requirements for installing.
So, when installing on a windows pc whithout quicktime, it does indeed not ask foor the quicktimeplugin, but when you try to actually run the screensaver, there's just a black screen whith yellow text, saying to install the quicktime plugin. How is this possible?
The avi file plays fine on it's own...
