Installation iTunes impossible

Lors de la dernière mise à jour de iTunes, le programme est devenu inaccessible. J'ai essayé de le réinstaller plusieurs fois, y compris en supprimant complètement iTunes de l'ordinateur, mais à chaque fois le message suivant apparait : "Echec démarrage du service Apple Mobile Device. Vérifiez que vous disposez des privilèges suffisants pour démarrer les services système".
Si j'essaie de démarrer tout de même iTunes, le message suivant apparaît : MSVCR80.DLL introuvable, puis "Réinstaller iTunes Error 7 (Windows error 126).
Que faire?

  • Windows installer erreur : impossible d'installer icloud ou Itunes

    Bonjour.
    Utilisateur de Windows 7 (64), je rencontre une impossibilité totale d'installer iCloud ou iTunes.
    Historiquement, j'avais installé le tableau de bord Icloud et au moment d'installer iTunes j'ai rencontré le message d'erreur suivant : "un problème s'est produit sur ce package Windows Installer.Une DLL nécessaire pour terminer cette installation n'a pas pu être exécutée. Contactez votre service de support ou le distributeur du package."
    En suivant les indications données par Apple, j'ai désinstallé entièrement iTunes et les composants Apple dans l'ordre indiqué. J'ai réinstallé iTunes en cliquant droit et en l'installant en tant qu'administrateur, mais une erreur est survenue. Cependant, le logiciel fut installé tout de même et fonctionnel. L'installation de iCloud n'a pas fonctionné, que ce soit par l'installateur d'Apple ou en téléchargeant le logiciel et en l'installant manuellement.
    J'ai recommencé la manipulation d'Apple, à savoir désinstaller tout.
    Cette fois, aucun des deux ne s'installe.
    Lorsque je lance iCloud en mode normal, l'erreur suivante apparait :
    "un problème s'est produit sur ce package Windows Installer.Une DLL nécessaire pour terminer cette installation n'a pas pu être exécutée. Contactez votre service de support ou le distributeur du package."
    Lorsque je le lance en tant qu’administrateur, une autre erreur survient :
    "Impossible d'ouvrir la clé UNKNOWN\Components\...\BD528ECCA74340041A68F5A4F6DD5874. Vérfiez que vous disposez des droits suffisants pour cette clé ou contactez votre service de support de support technique".
    Je vous prie de bien vouloir m'aider à résoudre ce problème et vous remerciant d'avance.

    SCAN your computer for possible WIndows system file corruption.
    Can you go to command prompt (START/ALL PROGRAMS/ACCESSORIES right mouse click "command prompt" and choose "Run as Administrator"
    type in
    sfc /scannow
    let Windows fix any system files that need to be repaired.
    Restart the computer.
    Then do the install.

    Repair your Apple Software Update:
    Go to START/ALL PROGRAMS/Apple Software Update. If it offers you a newer version of Apple Software Update, do it but Deselect any other software offered at the same time. Once done, try another iTunes install

  • Impossible installation itunes 11 car incompatibilité avec IOS7 de mon iphone. Je dois rester sur l'ancienne version d'itunes pour pouvoir l'utiliser mais mon iphone 4 ne s'y connecte plus. Que faire?

    Je ne parviens pas mettre en accord la nouvelle mise à jour IOS 7 de mon Iphone 4 (qui est médiocre pour l'Iphone 4 en plus) et la nouvelle version d'Itunes. Si je reste sur l'ancienne version d'Itunes, Itunes fonctionne mais mon Iphone n'est pas accepté et 'on me demande la version d'Itunes supérieure.
    Quand j'installe la version d'Itunes 11.1, un message apparaît : "un composant requis n'est pas installé. Veuillez réparer ou réinstaller Itunes. (-45075)".
    Que faire ?

    Bonjour,
    J'aurai aime vous aider, mais je ne comprends non plus comment cela est arrive.. surtout avec un shuffle tout neuf. Le mien a marche tres bien jusqu'a l'heure. Evidemment il doit y avoir un defaut quelque part avec les shuffles, et je comprends votre frustration. La seule chose que je peux vous suggerer est d'ecrire a quelqu'un dans ce site (c'est a dire un professionel), et attendre une reponse.
    Sinon, au moins vous avez encore la garantie, alors qu'il y plusieurs d'entre nous qui n'avons plus.
    Bon chance!
    (excusez mon francais aussi svp! et les accents qui manquent!)

    No, but you do not need iTunes to setup a new iPhone 5s. Create an iCloud backup for anything you want to transfer to the new iPhone.

    You can try disabling the computer's antivirus and firewall during the download the iTunes installation
    Also try posting in the iTunes forum since it is not an iPod touch problem.

    (1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
    http://majorgeeks.com/download.php?det=4459
    (2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
    (3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
    (4) In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove", as per the following screenshot:
    (5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

    The new cable is completely new, and my computer can detect the phone as a drive, and battery charging is ok. So I believe the USB cable works properly. It is so weird that just iTune itself cannot detect the phone, and it is of the most updated version. What else can I do? Thanks.
