You renamed the gtk DLL's, i assume you simply renamed them, but to get 
things working with different names you would need to build GTK from 
source, and apply the appropriate patches to GTK and its make files.

If you would use a dependency walker on libgtk-3-0.dll you can see that 
it depends on basically all the other dll's in the directory, and by 
renaming them they can no longer be found. For libraries that are in 
both GTK 3 and GTK 2 it might find the libraries distributed with 
gtksharp but that would also fail because of the version difference.

Printing the full path of the library in the error would only only be 
possible if we call LoadLibrary with the full path. It's been a while 
since i implemented the architecture check but if i remember correctly 
there were some issues with that. Otherwise it might be loaded from one 
of the other directories LoadLibrary searches, and then the printed path 
would be wrong, making things even worse.

And yes you could hard code the path that is passed to SetDllDirectory 
as a work around, but the dll's will need to have there proper names.
