I can not open MP4 files in windows vista, and I do not know which application I have to use. Windows media player seems can not play it.


WMP should download the codec automatically, but since it looks like something is interfering with this, please go to the following website and start by reading the “How do I find a codec?”. This will help you get the codec you need.
