Hi,
had a similar problem and solved it.
–U have to add the module to the name.uproject file.(watch how it in ur
c++ looks)–copy .dll and .pcb(maybe not needed) inside Projectfolder/Binaries/Win64
– modify UE4Editor.modules. Basicly copy from ur c++ project and remove
all modules u dont need in the artist
project.
Works for me 
Good luck
