Bonjour,
 
J'ai un soucis avec iTunes, je ne peux ni le désinstaller ni le réinstaller.
Une clés registre bloque la manoeuvre, j'ai essayé de la virée à la main. J'ai pas l'acces, pas les droits pour, pourtant je suis en admin et si je passe par le compte admin de vista, j'ai pas la main non plus.
 
Quelqu'un a une idée ?
 
 
J'ai passé un coup de Hijackthis dans le doute, mais je ne m'y connais pas donc je vous mets le log :
