I have adobe photoshop element 6 enregistred whith a valid sérial number. I have to reinstall it but the photoshop DVD is damaged
Where I can download adobe photoshop 6 and apply my serial number? (I find version 11 but no version 6)
Alas, a download isn't going to help you any, I'm afraid. For PSE 6, there were different serial numbers for the download version and disc versions and you can't use the serial number for one for the other. In any case, adobe doesn't provide downloads except for those who bought a download originally, and then only for three years, so there's nothing available from adobe.
