Nikon's software tends to be more useful than other camera manufacturers' self-produced software. But that's no better than the corporate mission statement, "We're no worse than the other guys".
When I got my Coolscan, I installed Scan 3 software. It crashed my computer 38 times in one weekend. It came with the manual that had installation instructions. Inside the booklet it had a replacement "how to install the software" section. After I installed it, I found a loose sheet of paper in the box that had "how to install software", which superceded the manual and the insert.
When I finally got a hold of tech support, they asked if I installed 3.0 or 3.1. All I had was 3. They said it didn't work. So I had to go to some hidden web page to download 3.1. The real story I heard goes that it was tested on a certain machine or similar machines and that they discovered that it locked up with machines that had a different brand of RAM that the machine(s) they tested with version 3.0. Ugh!
I think I will wait until the next version of the software before I even look at it, and then it might still be scary.
I updated from Nikon View 5 to 6 and lo and behold, Adobe Raw Converter would no longer work. I had to reinstall it.
