I have a EOS 5D Mark III. How do I edit RAW-files with Photo Shop Elements 10.0? Do I need a plug-in?
Load the editor, go to the Help menu and select About Plug-in -> Camera raw to see which version you currently have installed.
If you currently have a version before 6.7 then try going to the Help menu and selecting Updates - that may install camera raw 6.7 which you need.
If the update doesn't work, try a manual install
