Quote - I've been runiing PoserPro and P8 alongside each other with no problems, you should be fine.

How should I do this?  Do I simply run the installer and let it install P8 in its default location;  would that give me a Poser 8 folder beside the Poser Pro folder in the Smith Micro folder?  Or should I browse/create a custom P8 folder when I install?

Well, if I'm going to buy two more P8 licenses (for the 64bit Poser Pro machines), I may as well get the physical boxes, so that I'll get a couple of manuals.  I love an actual paper book manual. ^o^

Argh!  Both the P8 content zip and the legacy content zip give me an "unknown format or damaged" error.  The program installer archive unzipped successfully.

Poser 12, in feet.
