Quote - A big recommendation concerning Win7 and Poser runtimes.  Any content installed into Program Files will trigger UAC (User Access Control) which will interfere with Poser function.  This is true in Vista & Win8.  Poser 9 has default installation guidelines, place the application into Program Files folder but create a share folder under Documents for content.  By installing content in such location and keeping other external runtimes away from Program Files, you experience no UAC interference and no crashing.  

I might have to give that a try. Seems I spoke too soon. Poser loads now, but after adding a few low poly characters and doing a few renders, it does the same crash. It always crashes at the begining of a render after a few others have been done.
