There are two basic possibilities; 1) Windows is not finding/using the 
GraphicsMagick DLLs because they are not in the Windows search path or 
lack the necessary manifests to allow Windows to use them, 
or 2), the GraphicsMagick core DLLs are found but the coder modules 
and/or .mgk files are not being found.

I suspect that the problem is the first one.  Everything is easier 
with Windows when using a side-by-side DLL arrangement.  Otherwise you 
may need to spend a day or two studying and becoming an expert in 
Windows manifest files and perfecting an installer, as well as testing 
on many variants of Windows to make sure that things work.

I think that this one defaults to defined.  If it is defined, the DLL 
automatically registers its own location when it is loaded so that any 
argument you passed would be ignored (since it would be processed 
after DLL initialization).

Unless you enjoy intense frustration, the above seems like a wise 
plan.
