It hasn't worked. I downloaded Camera Raw and installed it in Presets but the program still says that it doesn't support RAW. I've just about given up and gone back to using DPP.

Dan,

If you tried installing a version of ACR later than 3.7, it WON'T WORK. Download v3.7 from here:
http://www.adobe.com/support/downloa...jsp?ftpID=3588

then follow the instructions I've pasted below.

After downloading a ".zip" file, use the operating system or a utility such as WinZip or PKZIP to access the file's contents.

To install with Adobe Creative Suite 2 or Photoshop CS2:

1. Exit Photoshop CS2.
2. Open My Computer.
3. Double-click Local Disk (C: ).
4. Navigate to: (Please read directory carefully)

Program Files\Common Files\Adobe\Plug-Ins\CS2\File Formats

5. Move the existing Camera Raw.8bi plug-in to another location (for example, a new folder on your desktop). Ensure you keep this version in case you need to revert back.

6. Copy the Camera Raw plug-in, Camera Raw.8bi, from the download into the same folder as Step 4.

7. Launch Photoshop CS2 or Adobe Bridge.

NOTE: If generic camera thumbnails appear in Adobe Bridge, follow the these steps:

1. Check to make sure the plug-in was installed in the correct directory in step 4 above.
2. Start Bridge.
3. Choose Tools > Cache > Purge Central Cache.

Important: Purging the Central Cache deletes cached thumbnail information for all folders. It also deletes labels, ratings, and rotation settings for read-only files (for example, files on a CD or locked files) or file formats that don't have XMP support.
