YIPPIE IT WORKS! I too found a key under "HKEY_CLASSES_ROOT/pz3file/DefaultIcon" that was pointing to an old installation (strange...I uninstalled before installing to a new drive...you'd think that wouldn't happen). I also had to manually add the "HKEY_CLASSES_ROOT/Poser3File/DefaultIcon" key...I had not "poser3file" key at all. I'm not sure why I would since I have poser 4. Maybe Poser3File was the key created by the Metacreations version and pz3file is the key created by the CL version?
