Okay, up front accept the fact that I am a computer idiot.  I'm a video editor and spend all my time keeping up on the latest advances in Avid and Aftereffects, so the internal mysteries of Poser and Vista Business 64 remain just that - mysteries.

I currently have Poser 7 installed on a i7 PC with 12 GB of ram and a Nvidia FX4800 video card.  It's running Vista Business 64.  I can't currently upgrade to Windows 7 due to the version of Avid I'm running.

Poser is installed on the C Drive under Program Files (x86).  All my Runtime files are there, too.  I don't currently have any external Runtime folders.

I want to install Poser Pro 2010 and keep Poser 7 on the computer - if possible.  If not, I need to access all my old Poser 7 Runtime files - figures, poses, props...

What is the best way to do this without causing conflicts?  I'm assuming I should put it on another drive.

Can and how can I access my Poser 7 Runtime in Poser Pro 2010?  Or do I have to reload all my stuff into Poser Pro?

Sorry for the obviously basic and probably stupid questions, but I need for this installation to go smoothly as a big job is coming up and I need  Poser Pro to speed up renerdering and to take advantage of the new lighting.

By the way, how much does Poser Pro speed up rendering in your experience?  I know it takes advantage of the 8 core system I'm currently running, and I'm hoping to see a good increase.

Thanks for any advice.
