I've thought about 4 or more Poser installs-- one for Fantasy, one for urban grit, one for fashion, One for sci-fi. I wait about 15 20 seconds and click cancel-- it usually has found both of my installs by then-- but not the cannibalised one on the auxilliary drive. I also like to install a lot at once, and I'm on XP, so for the next one I can cancel right away and it has the one I want to install to right in the window waiting. Emily
