Me again. I had Nikon Scan 3 installed on my old XP computer. I can install the same on this computer with no apparent problem, but there is, of course, no working driver
for Win 7. The system won't let me install Nikon Scan 4, in any of its iterations. I get the message I sent with my first post. I tried as both me and administrator.
I'd had the scanner working because I'd downloaded the trial version of Vuescan and it worked. I'd meant to go back and pay for it, but time got away from me & apparently the trial period expired. I'd like to get your fix working (won't cost $40), but can't find any way around the Nikon Scan 4 problem.
