I've been using Photoshop CS5, and just upgraded to and installed CS6. Suddenly, all my paper icc profiles (except for the Photoshop and Epson canned ones) have disappeared, and despite repeated attempts to reinstall them, Photoshop doesn't display them, not just in CS6, but also in CS5 (where they had been perfectly usable up until I installed CS6). I found a discussion of the problem in a Photoshop forum, but no useful solution was ever suggested in it.
I'm running CS under Windows 7, and trying to use Ilford and Moab paper profiles that had been working fine under CS5. My printer is an Epson 3880.
What is the experience of people here? Is this a problem for others? What solutions have you found?
