hi
i had a hell of a time getting nikon out

had to reinstall photoshop

did you go to adobe photoshop plug ins and remove the 2 nikon plugs
1 for raw the other ycc tiff

did you run regsweeper from nikon
you need to copy txt file has reg entries index

good luck
i later tried raw shooter
my machine is standalone
program kept trying to web register
