First, you must download Adobe Camera Raw Plug-In 4.1.1 here

To install with Adobe Creative Suite 3 or Photoshop CS3:
  • Exit Photoshop CS3.
  • Open My Computer.
  • Double-click Local Disk (C:).
  • Navigate to: C:\Program Files\Common Files\Adobe\Plug-Ins\CS3\File Formats
  • 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.
  • Copy the Camera Raw plug-in, Camera Raw.8bi, from the download into the same folder as in step 4.
  • Launch Photoshop CS3 or Adobe Bridge.

Note: If generic camera thumbnails appear in Adobe Bridge, follow these steps:
  • Check to make sure the plug-in was installed in the correct directory in step 4 above.
  • Start Bridge.
  • Choose Tools > Cache > Purge Central Cache.

Now you can open the .CR2 Raw files in Adobe Photoshop CS3.
