[Solved] no quicktime


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...


  • ...and the same goes for an mp4 file...

    Here's a screenshot of the error i'm getting:

    I repeat: i unchecked all requirements, and it indeed doesn't check for quicktime, BUT when starting the saver it displays a black screen with yellow text saying i need the quikctime player..
  • Hello -- please refer to which explains how to make a screensaver that doesn't require QuickTime.

    The quick answer is that you can only use Image or Flash content -- video format is not allowed unless QuickTime is installed.
  • Hello

    I have the same problem with quicktime.
    Does this mean i cant!! make a video screensaver that works on a Win mashine without quicktime????

    Please answer quick :)

    so long

  • Yes and no -- You can use Flash (SWF) to do video instead of QuickTime, in which case Flash Player will need to be installed on the Windows PC instead of QuickTime.
  • Please note that iScreensaver Designer 5 has been released which addresses this specific issue.

    Please see for a list of new features in version 5.0.
