I apologize, it is my poor explanation in the readme that is the reason for this confusion. PCM does not list the stuff already installed in your poser runtime. It works like this: You run it, let it go through the first scan, then you install something new into your poser runtime (still keeping PCM running), and then you press F12 to create a PCA file for those files you just installed. This way the PCA will serve as a more easily browseable replacement for the installation package you just ran to install stuff into your poser runtime. I'm just realizing that this is probably a bit unusual, but it was what I needed. Sorry for the poor explanation.
