Windows version of GraphicsMagick is available from the GraphicsMagick website. To read about the difference between ImageMagick and GraphicsMagick, check this out: » FAQ .

1.4+ is a mistype, I suppose. According to http://sourceforge.net/p/graphicsmagick/code/ci/tip/tree/ they don't even have 1.4 branch. The latest release is 1.3.18
