I have a major installing spree coming up, when I can face it - but I gave it a quick whirl on a couple of zips and a recent DAZ installer. All seemed to go well. I "installed" to a temporary folder anyway (no distrust implied, I do that anyway so I can put library files where I want them). One question though: when a DAZ installer has a choice between (say) DAZ|Studio / Poser 4 / Poser 5 etc., how does it know which option to choose?
