Well guess what...It did not work lol.  I followed the above instructions about allowing it to install to the default runtime location...then I installed v4 to the default runtime location.  With this dummy poser.exe.  Initialized and updated v4.

Open up Poser, look under figures in library for any trace of V4 and ....dun dun dun: Nothing.

I can access her from external runtimes still but I greatly prefer for my main figures to be located inside the main runtime.  It keeps things clean for me. 

Soooo what to do now?... :(
