My experience with node-imagemagick-cli is that it doesn't work if the "magick" executable's path (on Windows) contains one or more spaces. Since usually programs are installed on Windows under the "...\Program Files..." path it could be a common situation.
I've made a small change in order to make it work; I've tested it under Windows and under OS X. I don't know if it also works under Linux.
