You need to install the latest version of GhostScript before you can convert a pdf using Magick.NET.
Make sure you only install the version of GhostScript with the same platform. If you use the 64-bit version of Magick.NET you should also install the 64-bit version of Ghostscript. You can use the 32-bit version together with the 64-version but you will get a better performance if you keep the platforms the same.
