Micheal 5 is a morph of Genesis.  Technically it is not a Poser figure, to use it in Poser 9 you must have the DSON Importer add on ( a product at the Daz Store).  You would install the DSON importer add on to your main Poser runtime.  That product will include the Genesis starter essentials which you may install anywhere as long as you map the folder location in Poser.  Once you have installed the DSON importer add on and the starter essentials you just need to make sure that you install Michael 5 to the same folder as the Starter essentials and you should be good to go.
