I'm having trouble installing iTunes. I had it installed before, but it didn't work properly, so I unistalled everything (I think I got everything out, but it still says "apple sync notifier are failing to start" or something when I turn my computer on). Now, when trying to reinstall it, it doesn't work. I get the message: An error occured during the installation of assembly 'Microsoft.VC80.CRT,type=win32",version=8.0.50727.6195",publicKeyToken="1fc8b3b 9a1e18e3b",processorArchitecture="x86'". Please refer to Help and Support for more information. HRESULT: 0.x80070424.
I have windows vista, internet explorer and 64bits, thats the limit of my knowledge.
Does anyone have a clue about what i can do? I'm pretty hopeless at computers... Although I'm ok at installing things - normally.

Windows Vista, iTunes

    SCAN and repair 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 if it did actually repair any files.

    Start iTunes and see if it is ok.

    I'm not surer it it actually fixed anything, but I don't think so. I started it over anyways, and tried to download the correct iTunes again.


    By the way, I just checked, and when I turn my computer on I get two mesages up.
    1: Microsoft windows message: "AppleSyncNotifier has stopped working. A problem caused the program to stop working correctly. Windows will close the program and notify you if a solution is available."

    2: AppleSyncNotifier.exe - Unable To Locate Component. "This application has failed to start because CoreFoundation.dll was not found. Re-installing the application may fix this problem."'


    I have done something before to follow some guide to fix the applesyncnotifier, but it didn't work then, if that is the root of my problem.

    I'm having problems downloading other things too, like the statistics program SPSS. A "computer-guy" at work wasn't able to fix it, and said that something more basic seemed to be wrong. But he never looked at Apple-stuff...

    Fix 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

  • _Lizzzzz_ Level 1 Level 1 (0 points)

    One Safari and one iTunes update there, but none of them would be updated. I tried theit tip to do it manually, but that did'nt work either...

  • wiclee Level 5 Level 5 (6,950 points)

    So you don't see an Update for Apple Software update?


    Then go to Control Panel, Programs n Features, highlight 'Apple Software Update', and click Repair button.

  • _Lizzzzz_ Level 1 Level 1 (0 points)

    When I did the search Start, all programs, apple software update it said Safri 5.1.2. and iTunes 10.5.3.
    So I saw that, and then I tried what you said with control panel, programs, features, and repaired Apple software update. I don't know if it rapaired anything, but if it did it happened very fast. Tried restarting and dowloading again, as I do all the time:p

    OK, the best thing now is do the uninstall and reinstall from scratch.


    Try the following steps:

    1. First, go to Microsoft website to fix install and Unistall problems. Click "Run now" from Fix it to remove all iTunes & related installer files:

    Be aware that Windows Installer CleanUp Utility will not remove the actual program from your computer. However, it will remove the installation files so that you can start the installation, upgrade, or uninstall over.




    2. You should remove all instances of iTunes and the rest of the components listed below:

    it may be necessary to remove all traces of iTunes, QuickTime, and related software components from your computer before reinstalling iTunes.

    Use the Control Panel to uninstall iTunes and related software components in the following order:

    1. iTunes
    1. QuickTime
    2. Apple Software Update
    3. Apple Mobile Device Support
    4. Bonjour
    5. Apple Application Support (iTunes 9 or later)

    Follow the instructions from Apple article listed here: to remove all components




    3. Reboot your computer. Next, download iTunes from here: and install from scratch

    Shoot, I did all that, but the installation still stops with the message at the very top of this conversation.
    But I did still have some "residue" with bonjour istalled, and one file with quicktime. But they are now gone, from everywhere. After I clicked that message away it said: "Service 'Apple Mobil Device' (Apple Mobile Device) failed to start. Verify that you have sufficient priviledges to start system services."
    I looked for apple mobile device and I see that suddenly Bonjour has come back... whaat? I'm going to try and get rid of it again...and then try restarting and

    installing again...

  • _Lizzzzz_ Level 1 Level 1 (0 points)

    After all "residue" was gone i got the same message as at the far top, but i got further, and this came up:
    "Apple Application and Support was not found. Apple Application Support is required to run iTunes. Please uninstall iTunes, then install iTunes again."
    I've done that about 5 times now.

    Hmm!! Since all the possible soultions have not worked, I would like you to do two things:


    1. Please check if you have all the updates and special Packs installed on your Vista. If not, please update them.


    2. I suggest you SCAN your system for possibe Malware in Windows Safe Mode". Log on into Windows "Safe mode with networking", then go to CNET's to download a free version of MALWAREBYTE. Install and do the update immediately. Perform FULL SCAN and remove the Malware if it indeed finds any. Restart to regular Windows to let MALWAREBYTE remove those trace in the registry. Then try your iTunes again.


    Good Luck!!


    Here is how to start windows in Safe Mode:

    To start your computer in safe mode

    Press and hold the F8 key as your computer restarts. You need to press F8 before the Windows logo appears. If the Windows logo appears, you'll need to try again by waiting until the Windows logon prompt appears, and then shutting down and restarting your computer.

    1. On the Advanced Boot Options screen, use the arrow keys to highlight the "safe mode with networking" option, and then press Enter.
    2. Log on to your computer with a user account that has administrator rights.

    When your computer is in safe mode, you'll see the words Safe Mode in the corners of your screen. To exit safe mode, restart your computer and let Windows start normally.

    I'm having the same problem on both my ipad2 and my windows 7 laptop.  can connect to itunes store but when i download a purchase the connection times out.  please help

  • _Lizzzzz_ Level 1 Level 1 (0 points)

    I¨ll do that, but what are special packs? What should I look for? Can I just seacrch for what you now (possibly) mention and upload them?
    We'll fix this in the end, I've got faith!

  • wiclee Level 5 Level 5 (6,950 points)

    Go start button, type in Windows Update then ENTER. It will launch Windows Update Page, on the left Pane, click 'Check for updates', this will gives you all the updates available including Special Packs, if any. Install them all.

  • _Lizzzzz_ Level 1 Level 1 (0 points)

    As normal, it "cannot search for updates", so I'll try the safe mode thing.
