I have Vu e4.2 installed as well as Poser 4 and Poser 5. I don't use much Poser 5 yest, because I need to learn it. But I can import both Poser4 and 5 pz3 files into Vue 4.2, in doing this: I have Poser 4 on one HD and Poser 5 on another HD. I have renamed both folders to simply "Poser". First time I open then Vue 4.2 and try to import a pz3 from Poser 4 OR Poser 5, Vue will ask me again to locate Poser.exe. I locate the one or the other (from P 4 or P 5) and it works. Later it will work from both folders, as they have both the same name and Vue understands it should import from a "Poser" folder:-)
