You shouldn't install to the application folder - it's no longer the default location for the main Runtime folder, and is an actively bad idea if you are using Windows Vista or later (unless you have turned all the security features off). The default location for the Poser content is in Smith MicroPoserPro 2014 Content in your Public Documents folder, as I recall, so you should either install V4 there or to another content library if you want to keep the V4 stuff separate from the base content - in any event, you should uninstall the files you placed in the application folder as Poser will find the readscripts there and if you later install other morph expansions that could cause conflicts.
