Important advice, whenever you post a thread question, always include which Poser version and current SR packs you are using.  It will give those responding a reference towards answering correctly, rather than random answers which may not have any relevance to the app you are using.  Suggesting EZSkin developed for P9/PP2012 will not help you much if Poser 7 is installed on your system.  Also, include which computer OS you are running.  Many users have installation problems unrelated to Poser but, yet, interferes with it's function.
