Itunes won't launch anymore: AVFoundationCF.dll problem

Hi,
since my last itunes update, it won't launch because of a "AVFoundationCF.dll" problem. I'm on a Windows XP system. Can anyone help me please?

Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
Let's try something relatively simple first. Restart the PC. Now head into your Add or Remove programs control panel, select "Apple Application Support", click "Change" and then click Repair.
If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post (although it's for Vista and 7, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things):
Re: I recently updated to vista service pack 2 and I updated to itunes 10.2.1 and ever since I did that my itunes won't open any more.  Itunes starts but before anything loads a window pops up saying that the prograam has encountered a problem and sh...

  • IPhone 3rd party apps won't launch anymore!

    After updating the iPhone software to 3.1, a host of 3rd-party apps won't launch anymore (appear for 1 second, then revert back to the apps icons page).
    I've tried upgrading to iTunes 9, uninstalling then reinstalling ALL apps on the iPhone via iTunes, hard rebooting my iPhone, restarting my iMac, etc etc, but nothing works.
    On a iPhone 3Gs page on the Forums, I saw many others having similar difficulties and blaming it on the XX upgrade. One solution proposed there was to download a free app from the App Store and install it. Tried that, and it didn't work for me.
    I hope Apple will give this attention, because it's basically disabled my iPhone's business-sensitive functionalities (like 1Password) on the eve of a 2week business trip ... and on business trips, I don't have my iMac with me! >:-(
    In case it helps the OS is showing as 3.1 (7C144) on my device.

    Hi!
    I may have a solution to your problem. I updated to Firmware 3.1 today and couldn´t open any application i downloaded. I seems the updated version of iTunes handles apps a little different from before. When you connect your iPhone and it pops up in iTunes, right click on it to enter your configuration area (for the iPhone). At the top bar you have a row of options like music, pictures, podcast and somewhere in the middle you have the option "Programs". Click on that and you will see a list of all the programs you have downloaded in iTunes. Unfortunatly you have to recheck all the boxes at the left side of the program you want to be synched to your iPhone. Check these boxes and click "Apply" at the bottom right and iTunes will now transfer them to your iPhone. Easy breasy when you know how to do.
    Best of luck, Cheers!

  • My itunes won't launch even after reinstalling.  Looked in itunes folder and somehow lost itunes library?  HELP!

    My itunes won't launch even after reinstalling.  Looked in itunes folder and somehow lost itunes library?  HELP!

    The first thing I'd suggest is to get a good antispyware checker and give it a go at your system. Some recent spyware has been reported by other users to shut down iTunes or prevent it from launching. From user reports, Ewido seems to be the best at catching it. You can download a free version of Ewido here.
    If that doesn't cure the problem, try deleting the iTunes preference files:
    C:\Documents and Settings\<username>\Application Data\Apple Computer\iTunes\iTunes.pref
    and
    C:\Documents and Settings\<username>\Local Data\Application Data\Apple Computer\iTunes\iTunes.pref
    You might have to turn on "show hidden files" to find them. (Right click "my computer", select open, select Tools menu -> Folder Options. Select View tab, "show hidden files" radio button is in the center scrolling panel.) Delete them or if you want to be able to put them back if it doesn't help, drag them to some other location. This will force iTunes to run the setup assistant the next time you launch iTunes. Note that you'll have to go back and set any preferences you've changed from the default.
    If that still doesn't work, try this:
    Bugie: Perform a Thorough & Complete Uninstall and Reinstall of iTunes/QuickTime.
    Hope this helps.

  • Itunes won't launch since update

    Seems like i have the same problem as a lot of people.
    Since last update itunes won't launch
    Just get a white screen and the blue circle going around the pointer.
    Have tried the complete unistalll and reinstall without success
    One thing i noticed is that when it freezes and i open task manager to close it down it says 32 bit next to itunes not 64 bit?
    Is the wrong version being downloaded?

    Without trying to be funny here, why should the problem be with my user account or my PC!
    Without trying to be funny, you've accidentally succeeded in being a bit funny here.
    This is a user-to-user troubleshooting forum. Folks come here to troubleshoot their problems. So we, quite naturally assume that's what you were trying to do, and reply to try to help you fix it. The reason why you see so many people here saying there are problems is that this is where people come if they have problems and want to fix them.
    If you believe the problem is all at Apple's end, and would like to register a sort of complaint with them (rather than do any troubleshooting of your problem), then it makes a heck of a lot more sense to contact Apple directly via the product feedback pages. (Because this is primarily an user-to-user forum, there's no guarantee an Apple person will see your post here. They will read your feedback via the form, although they also say they will not respond.) Here's a link through to the iTunes product feedback form:

    (Given that you're not here to troubleshoot, I'll bid you adieu, and desubscribe from this particular topic.)

  • Microsoft Office X- won't launch anymore

    Hi:
    I have Microsoft Office X- All of a sudden my Microsoft Office Apps won't launch anymore. They report an error yet if I open a document it will launch Microsoft Word or PowerPoint just fine.
    I have tried to replace the Microsoft Office X from a Super Duper back up but it also is still failing to launch.
    I am guessing "launch services" is goofed up. Does anyone know how to fix this issue?
    Thank you,
    Reid

    I don't think it is an Intel based problem. I have a G5 iMac and a legal old MS office v.X upgrade on top of office 2001 version. Worked fine until a few weeks ago except for a few years needing to keep current with the latest XML free MS converter. Repaired disk/permissions. Dug out all of the app/preferences from my user/library. Reinstalled and it checked with MS mothership. However, still crashes on launch. I think perhaps the most recent OSX security update?

  • ITunes won't launch if iPod is connected but ejected

    If I connect my iPod (set to Disk Use, no auto-launch of iTunes), then eject it through the Finder, iTunes won't launch. It hangs with no window until force quit or the iPod is unplugged. I've noticed this through several versions of iTunes.
    Note that I found this topic already in existence here, but I felt that the issue needed a bump to the top of the list.

  • ITunes won't launch after upgrade

    I just downloaded the new iTunes upgrade onto my Macbook, and now iTunes won't launch. It just bounces once and then does nothing. I've gone through the uninstall and reinstall process, but still no dice. Any suggestions would be greatly appreciated. (Also, since I uninstalled it, did I lose everything I'd previously downloaded to iTunes?!)
    **I just realized I've accidentally posted this under the Windows discussion. Sorry.

  • Itunes won't launch after using norton utilities

    Hi,
    I used Norton disk doctor and now itunes won't launch. How do I fix this?
    Many thanks!

    Get rid of Norton's, it's far more trouble than it's worth. This is exactly the kind of thing that happens when you run Disk Doctor or the other parts of the suite, and is why they got out of the Utilities market for the Mac.
    1. Try repair Permissions with Disk Utility
    2. Try Trash the com.apple.iTunes.plist file from the home / library / preferences folder
    3. Try Re-install iTunes. Move the app from the Applications Folder to the Trash, then go to HD / Library / Receipts and trash any pkg file there with iTunes in the name.

  • ITunes won't launch in Windows 8

    Recently bought a new laptop which came with Windows 8. I cannot get iTunes 11 to launch in Windows 8. Whenever I launch it, I simply get a completely white screen and Windows Task Manager reports it as "Not Responding." I have attempted to "Repair" the installation, uninstalled, and reinstalled iTunes multiple times (I've also tried running Apple Software Update as well).
    On a somewhat related note, Quicktime won't launch either. I can double-click the icon on the desktop as much as I want, but the program simply won't launch, at all. Windows Task Manager doesn't even display it as an active process.

    If you are still having this problem, Sony Singh posted this fix in another conversation, and it worked!  I have the same Windows 8.1 and iTunes version you have and had the same problem.  This totally fixed it.
    Copy QTMovieWin.dll from:  C:\Program Files (x86)\Common Files\Apple\Apple Application Support
    to: C:\Program Files (x86)\iTunes
    Simple, huh?  Just reboot after youo copy and paste the above file.
