Ok unfortunately I've gotta head out for awhile today, but for now I just downloaded the VSS files and the update file to the D3D.

At a quick glance it looks like the VSS has instructions on the website that says to unzip one to its own runtime, then unzip the other over that one.  Seems simple enough. 

But the D3D update is just a zip file that contains two "py" files and two "txt" files.  Couldn't seem to open the txt files to see if they were instructions on how to install...ie...which poser folder to unzip them to.

Will check the website again later.
