Sure. Here's the embedded store in Poser 12's library. It's the last tab on the right. When you click it, it offers 3 different repositories: Included, Renderosity, and PoserSoftware. The first one is for installing contents bundled with P12, like the HW figures. The 2nd is for content purchased at Rendo. The last one is for content sold exclusively at PoserSoftware, such as Poser itself. The P12 scripts should be in the Renderosity section.
