Photo Shop CS4 version 11
Camera Raw 18.104.22.168
I had another version of Camera Raw from PS3. When I bought the Canon EOS 5D Mark II, I deleted the old camera raw plug in, so as to not conflict with the new camera raw plug in.
When I open PS4, click Photoshop, click about plug in, ONLY one version of Camera Raw comes up.
In OS 10, when I click GO at the top, then applications, then Adobe Photoshop CS4, then Plug Ins, then File Formats, I get two Camera Raw icons: a blue lego like icon that says "Camera Raw.plugin" and another icon that looks like the Macintosh HD icon, but is labeled "CameraProfiles.dmg"
The problem is that I can't open files in Camera Raw when in Bridge CS4, nor can I see the little photo thumbnails either.
The Photoshop folder is NOT the correct location for the Camera Raw plug-in, since several versions of Photoshop.
The correct location, is, as described in the readme and in the FAQ of this very forum [hint]:
Mac: [root of your hard disk, NOT your user folder's library]/Library/Application Support/Adobe/Plug-ins/CS4/File Formats/
