**V4 should install to the application runtime , and NOT to an external runtime if possible. There are a couple of special folders that V4 MUST have available or it doesnt work properly.

If you can load v4 I would reinstall it to the poser 7 runtime. The daz installers should put everything in the right place if the install path given it is
c:/program files/e frontier/poser 7   or wherever your Poser 7 was installed .
