Have latest Poser update??  This update creates an addon folder . I had problem also and thought my Poser2012 was up to date. Getting any errors?  Also I was asked to open poser and check top task bar..Windows...See if on bottom there is a folder called Addons...Now shows up both in my Win XP and Win7 64 bit...Still an idio how to use Reality3 but that is something I will work on
