Just another hint: Poser11 is the last one to be installed within "Program Files". Poser12 and the next versions will always have their own tree, elsewhere. Actually: on a dedicated partition stored on a Samsung SSD 860 M.2, with all my runtimes (I've seen a difference in speed when I did this)
The "Program Files" zone is too strict, too complicated to manage.
And as you can see, all scripts such as EZSkin3 and the likes are stored on a third drive.
