The zip setup and naming from DAZ3D is exclusively designed for DIM, and only DIM will automatically install content properly into DAZStudio and Poser. Manual installation is fine also provided that you know exactly what you are doing and familiar with the folder hierarchy structures for both programs. You cannot install Renderosity, RuntimeDNA, etc zipped files dedicated for DAZStudio using DIM; usually vendors will provide written instructions in a text file on manual copying folders and files to their final destination.
