Quote - i have 4, 4.1 and 4.2 installed and i can use them all without issue, if you let the installer do its thing, you should have no problems what so ever :)

I haven't installed V4.2 either. I was told that when you install V4.2 it overwrites V4.1

So far as installing V4.2 to a temporary directory and manually moving the files, how do you do that? When I installed V4.1 I couldn't install it to any folder other than the main Poser 6 runtime. I assume that it's the same for V4.2 as well.

able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
