I recently installed Studio 2 and Adjust AI. Now the filters menu in CS6 (Win 8.1) also lists Sharpen AI and Denoise AI, neither of which do I have. The primary issue is that if I accidentally click on one of these choices it crashes photoshop and my work is lost.
After some back and forth with support, I tracked down and deleted references to Denoise AI and Sharpen AI in a couple of folders on my system. Support tried to blame Photoshop but two of the files I got rid of were .8bf files, which are the actual plugins. Since I never installed either Denoise or Sharpen, where did they come from? Photoshop did not spontaneously generate them.
At any rate, the phantom entries are gone and there will be no more crashing of Photoshop due to my inadvertently selecting them.
