I also noticed that your icon associations are all screwed up.  The CR2's should be referring to the PoserPro icon, not IrfanView.  As WandW posted, the morph pack should be installed into the exact runtime as the base model.

BTW, the correct and official name for your Poser Version is PoserPro.  Everyone will know exactly how to better respond to queries if you use the appropriate version title.
