Ben mince alors... C'est pourtant bien comme ça qu'on fait :

For Camera Raw 3.6:
This new version of the Camera Raw plug-in replaces the original Camera Raw plug-in that was installed with Photoshop CS2, Adobe Creative Suite 2, or Photoshop Elements 3.0 or 4.0.

To install with Adobe Creative Suite 2 or Photoshop CS2:
1. Exit Photoshop CS2.
2. Open the Finder.
3. Navigate to: (Please read directory carefully)

Library/Application Support/Adobe/Plug-Ins/CS2/File Formats

4. Move the existing 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.
5. Copy the Camera Raw plug-in, Camera Raw, from the download into the same folder as in Step 3.
6. Launch Photoshop CS2 or Adobe Bridge.

Désolée, je peux pas t'aider plus que ça...
