yeah, I could be wrong – It wouldn’t be the first or last time, but I’ve seen a aweful lot of threads complaining that you *always* get the uac popup in Vista for installs and I’ve seen a fair number of threads about troubles with uac doing the same thing for click once. But none of this is really the point (and I don’t mind being wrong or corrected) as the thread was about if or how to change the location of the ds files for twain, seems that we’ve rambled away from the question. Wonder if he ever got a workaround for the original question.
I had some half baked ideas about copying twain_32 into the app directory and loading that version, but I didn’t have time to check if that would work or if they were too many dependencys for it to be anything other than a poor|awkward solution.
