You just add the p7 runtime as an additional runtime, just like you did with poser 5,6,and 7.

How do you do that?  Poser 7 was my first version of poser.

You weren't using the 64 bit background render engine you should have been using.

So the default renderer is broken now?

Sounds like a bad install to me, or possibly not applying the recent sr1 patch.

I applied the patch. But I will try what you said. I'll uninstall and reinstall then apply patch.
