The list at the side containing the runtime, if you click to go up a level you will see two folders, one for Poser5, one for downloads. At the very bottom of the list there is a plus and a minus sign, when you click the plus it gives you a browse list and you just locate your other runtimes and click ok. Works like magic and I've discovered since I did this a couple of days ago that Poser seems to be much more stable with the runtime on the other drive. 8) Catlin
