When V4/M4 are first initialized numerous absolute references are written in the morph channels which are valid as long as the original directory structure is maintained. If the install directory changes the morphs will no longer work. The references are absolute and not relative so any change to the original install location will "break" the figure. If this is a reinstall simply put them in a directory structure which matches the original. Use notepad++ (or notepad) to open the file in your RuntimeLibraries!DAZVictoria 4V4BODYChnnls.pz2 to verify the original installation directory structure; do not try and edit this file to correct the directory structures unless you want to spend a long and frustrating time editing because this is not the only place this method of referencing is used by DAZ. After you know where the files need to go simply place them there; that's why I still have an old Smith Micro Poser runtime on my "C" drive after numerous computer rebuilds, It was easier to do this then a reinstall of V4/M4 since the version which I have uses the old installer which throws errors after every install and doesn't even recognize Poser Pro.exe as a valid Poser executable.
