I'm trying to upgrade PP to 4.3 but for some reason altho it says it's found where the files are installed when I click ok it says that it can't find a valid poser pro pack installation. I have a legit copy of PP (an upgrade from poser4...from 3...from 2) I only installed P4 then upgraded with PP anyone know why I'm getting this error when it appears that the path is correct? Fang.
