Perfect. Thanks for that. Just finding something on this site was painful. You are great!
No problem. You were lucky. It's usually much messier than that!
Actually, It was a little messier.
After clicking the install, it turns out that it didn't place the camera Raw file in the right place. Had to go to program files (x86)/adobe/elements and Organizer. Then I looked for all the "file formats" folders. Then I inserted the camera_raw.8BI it into both the organizer and the elements directories (in plug-ins). Just to be on the safe side I put it in the local folder's plugins/file formats too. I put it pretty much anywhere there was a File Formats directory.
Once that was done, I used Organizer to open an ARW. It worked! Then I selected edit with Elements. It brought up Camera Raw! Did a save from there and Presto! Elements opened the picture for the first time. Sigh...
So now I can get them open, mess with them, and output them to a format that the rest of the world can recognize.
Again thanks for pointing me in the right direction.
Glad it helped.
A word of warning though: having more than one copy of the plug-in is potentially a recipe for disaster. I'm not sure about Elements, but in CS5 multiple copies of a plug-in are all located and can conflict. This may not be a problem now, but it may be if you update your software in future. According to Adobe's instructions, it should be located in:
C:\Program Files\Common Files\Adobe\Plug-Ins\Elements 8\File Formats
