I used to get a warning about a bad .dll every time I opened up Poser. I had to hit okay twice before Poser started. I found the .dll and deleted it. Now it complains about a missing .dll and not being able to initialize the application. I hit okay 1 time and Poser loads without any problems. Don't know, don't care. It works. I didn't even have to sacrifice a live chicken this time around. btw: Poser Pro Pack is a more up-to-date version of Poser, so the 4.2.160 is okay. (I don't have Pro Pack installed right now so I don't know if that is the latest version or if there's another patch or two available.) Poser 4 is only at 4.03.
