Keep in mind, the older generation 4 figures were primarily developed for use in Poser as well as other props and scenes. Once Genesis and Genesis 2 were released and relied on DSON to import those figures into Poser, DAZ decided to make CF's to accommodate the generation 4 figures and changes in DS. Your only option is what 3doutlaw posted, install the Michael 4 Base into a separate folder containing a runtime, and linking the folder to DS. This is a better option than moving files around and essentially breaking the figure.
