I finally found the IPB prep. They were located in the Support Files folder of IPB. They don't install automatically into PoserRuntime. You have to move them manually to RuntimeLibrariesDAZ and RuntimeLibrariesPose. I applied it to a V3 character I created. I suppose it does remove the Morph Delta's although I don't know how to check it. But I'm not sure it's the point because when I try to load it in IPB, I still get the "Please load a source file to continue" message when I hit Process Options.
