Using Windows 7, graphics card upgraded with current version and all requirements met I have tried all recommendations made in each of the blogs and I still get the message:  Movie Maker will not start.  It worked previously but then stopped when I downloaded Essentials 2012, thinking I did not have the current version, when I did.  I downloaded the patch (KB2741355) and it still did not work.  One of the blogs indicated the patch did not fix the problem and the is apparent. Since it worked previously I know the graphics card cannot be the problem.  Is there anything else I can do to get Movie Maker to work?
