I use Mac OS X 10.4.11. I run Photoshop CS3 in Rosetta, basically because that was the only way I could install Nik Sharpener Pro 2. Ever since then I've been unable to update CS3 and Camera Raw, I didn't really bother about it, because it did everything I wanted it to do! But I now need to update Camera Raw because I've just gpt a Canon 5D MkII.
Anyone any idea how to stop running in Rosetta and revert back to normal?
