I'm running my Poser from an external harddisk. I't's only installed on my computer to help me get the file associations. Poser can theoretically run from anything. I've run it from a CD and a flash drive (USB stick)  just to prove a point :)

so just copy the whole Poser 7 (or whatever version) over to the new disk, make a shortcut to Poser.exe and that's it. :) Easy-peasy.

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
