C'est indiqué sur le site Adobe :
"
The Camera Raw 4.2 plug-in is not compatible with versions of Photoshop earlier than Photoshop CS3 or versions of Photoshop Elements earlier than Photoshop Elements 4.0 for Macintosh or Photoshop Elements 5.0 for Windows. The latest versions of the Camera Raw plug-in available for previous Adobe software titles are listed below:
Mac
* Photoshop CS2: Camera Raw 3.7
* Photoshop Elements 3.0: Camera Raw 3.6
Windows
* Photoshop CS2: Camera Raw 3.7
* Photoshop Elements 4.0: Camera Raw 3.7
* Photoshop Elements 3.0: Camera Raw 3.6
"

Donc pour moi avec Elements 5.0 ca devrait le faire .... mais j'ai du louper une étape !
