I deactivated and uninstalled iClone 7 and 3DXchange Pipeline and found I could still export to FBX and import it into Blender. I noticed no difference in CC3 functionality at least as far as exporting is concerned.
Hmm. Maybe you only need 3DXchange if you want to import your own prop, hair, cloth or anything that you created in a third party software or market like Daz.
