You don't need the user-facing files from the DSON Core installer, if you are doing things manually you just need the /Runtime/Textures folder and the /Data folder (the /Data folder goes in the folder that holds the /Runtime folder). So you have C:/Users/Public/Documents/Poser # Content/Runtime and C:/Users/Public/Documents/Poser # Content/Data if your Poser library folder is C:/Users/Public/Documents/Poser # Content, for example.
