DimPro (and Rapture) have two folders a lá the microsoft standard for XP and beyond. In fact, there are several folders scattered around, once again, I believe, to conform to MS standards.
With the Cake synths I just let them install to their defaults. I've installed DimPro on two or three new computers and never had a hitch. Remember to hit F5 (refresh browser).
I remember the missing disk error from a long while back - maybe a search is in order. I never suffered that problem so I never paid attention to the thread or two that popped up.
