AVfoundationCF.dll is missing, windows 8

after the newest update for itunes it has ceased to even open. Two error messages come up when trying to open itunes, in the order shown.
My operating system is windows 8, and I have uninstalled and reinstalled multiple different ways.

Hey there Jklubak!
Try using the information in the following article to help you successfully uninstall iTunes:

Use the Control Panel to uninstall iTunes and related software components in the following order and then restart your computer:
iTunes
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support (iTunes 9 or later)
Important: Uninstalling these components in a different order, or only uninstalling some of these components may have unintended affects.
Take care, and thanks for visiting the Apple Support Communities.

  • When opening iTunes I continue to get the same messages, 'The program can't start because AVFoundationCF.dll is missing' and 'iTunes was not installed correctly. Error 7 (Windows error 126)' I've uninstalled, reinstalled many times - nothing! help please.

    When opening iTunes on my new Windows 7 PC I continue to get the same messages, 'The program can't start because AVFoundationCF.dll is missing' and 'iTunes was not installed correctly. Error 7 (Windows error 126)' I've uninstalled and reinstalled many times to no avail, even tried it on a different user account and still nothing. I recently installed Panda Internet Security 2012 (about 12 days ago), initially iTunes worked fine as usual but within the last few days I've been  unable to open it with the same messages appearing. I've read through some of these pages and tried everything that's been advised, uninstalling and reinstalling while internet and laptop security is swithched off, downloading tools to completely remove anything related to iTunes, tried it in Safe Mode, nothing has worked. I've also noticed that in the start menu when I click on iTunes, it says '(empty)' where it should have the logo and ability to start the program, does this mean it doesn't download + install properly each time I've tried? Any help would be enormously appreciated.

    Doublechecking. Have you also tried the following user tip?

    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. If you're using Vista or 7, now head into your Uninstall a program control panel, select "Apple Application Support" and then click "Repair". If you're using XP, 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. (If you've got XP, although the procedure is 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.)

  • AVFoundationCF.dll is missing from you computer

    “AVFoundationCF.dllis missing from you computer” This is the error message I got whentrying to start iTunes on my windows 7 professional x64. It alsoincluded the message “itunes was not installedcorrectly.error 7 (windows error 126)" so Ilooked around for a solution. What I found on a thread on Applescommunity was ridiculous, telling me to repair my windows. I lookdeeper when I found a solution my self. I thought I'd do all thepeople on the community a favor and reply on the thread but it wasarchived with out a solid solution.
    If any other peopleare getting this error message then this is what worked for me:
    Control Panel >Programs and features
    Right click on Apple Application Support, choose REPAIR.
    That did it.

    This worked for me, thank you very much

  • ITune dowmload on Vista problems. AVFoundationcf.dll - error 7 (windows error 126) and iTunes helper not instlalled properly.

    I've downloaded, redownloaded, uninstalled ,installed, ran sfc/scannow.  Nothing is working - am I missing something so simple that I'm just not seeing it?
    I have Windows Vista on a dell - am I really this stupid?

    I've been to the link above.  I did everything that was recommended.  I've deleted all Apple products from my computer and re-installed.  I've shut off my firewall & anti-virus.  I've tried usind IE, Google Chrome & Firefox and I keep getting the same error.  Please - why can't I install iTunes?

  • How do i fix itunes, AVFoundationCF.dll missing (error 7, windows error 126)

    I tried to update itunes to 10.5 but wouldn't install. I then tried to uninstall and reinstall and have had problems ever since. I tried removing every apple file on my computer( itunes, bonjour, etc..) with REVO uninstall. Then reinstalling to no avail, I receive AVFoundationCF.dll is missing follwed by error 7 windows error 126. I have been at this all day, and has really gotten me frustrated. I have searched through these forums and tried different solutions people say have worked for them but not for me. My last resort is to wipe my system and restore to factory settings, which I dont want to do. Can anyone offer some advice? Thanks

    I just found out why it was throwing out those error, you have to do a complete cleaning of your cache, it retains all the Apple information for some reason. I used a cache cleaner, but you van use the cache cleaner in Windows 7 or Vista 64 bit for this. Now Itune downloaded but without installing Quicktime. I actually like that.

  • HT201210 missing avfoundationcf.dll

    When I tried to install my updated Itunes  received the follow error message "The program can't start b ecause AVFoundationCF.dll is missing from computer. How do I fix this problem, help, help?!

    For general advice see Troubleshooting issues with iTunes for Windows updates.
    The steps in the second box are a guide to removing everything related to iTunes and then rebuilding it which is often a good starting point unless the symptoms indicate a more specific approach. Review the other boxes and the list of support documents further down page in case one of them applies.
    Your library should be unaffected by these steps but there is backup and recovery advice elsewhere in the user tip.

  • Error 7 (Windows error 126) avFoundationcf.dll not found.

    Error 7 (Windows error 126) avFoundationcf.dll not found. windows 7 64bit, I've tried everything, but it dosn't work, please help.

    Update .netframework to latest version (see apple support)
    then
    Follow the instructions on this link, basically un-install everything, remove programs that says they are made by apple inc. (using add remove program)
    http://www.reimageplus.com/fix-windows-127-error/   (Many thanks to reimageplus.com)
    You will also need to check and verify that the following folders have been removed:
    C:\Program Files\Bonjour
    C:\Program Files\Common Files\Apple
    C:\Program Files\iTunes
    C:\Program Files\iPod
    C:\Program Files\QuickTime
    C:\Windows\System32\QuickTime
    C:\Windows\System32\QuickTimeVR
    dont forget to remove icloud also
    you dont need to delete your itune music library though
    If any of these folders still exist, delete them along with their contents. (if you cant delete them, right click and go to properties and then security and change the control of the fold to you)
    do this for files under  program files and program file (x86) on your computer
    once you have deleted everything, restart your computer. Then I repaired my registry using a registry repair program.
    Important:-  instead of installing itunes I installed quick time, which installs apple application support (this is the corrupt file which is causing all the issues)
    i then installed itunes and it all worked fine,
    should take no longer than half hour to fix
    hope this helps

  • After installing update itune 10.5 will not open or run on windows 7 pc keeps telling me error 7 126 and that AVFoundationCF.dll failed to load. reinstall.I have done the complete 6part unistall 10 times now and each time I get the same thing anyone have

    So I installed the latest update of Itune on my Windows 7 Ultimate 64 bit PC.( the previous versions worked fine never a problem)
    It installs, and comes up with error7 126. Reinstall program again.
    So I go through all six steps to unistall, and reinstall a frsh downloaded compy of 64 bit Itune from Apple Site. and reinstall again and again, went through this process 10 times still having same problem, including now also comes up with AVFoundationCF.dll missing, try to install that won't install.
    So now I can not use anything apple, iteunes, safari, update etc, nothing will work, which means I can no lobger sync or update my Iphone 4S.
    Does anyone have an answer for me????

    I'm an applications developer and also run a part-time videography business. As such, I require more than 3.12GB of RAM. That is the physical limitation of a 32bit system. Pointless to stay on 32bit if you plan on having more than that much RAM.
    I'm also not about to pay someone to fix my PC when I can do it myself. I was originally hoping for someone who had experienced the problem before to point me in the right direction so I didn't have to spend so much time trying to figure out what the issue was for myself.
    Basically, in the end the problem was caused because right at the point in time when I chose to uninstall, and reinstall; Apple released a new version of iTunes. This version in turn had a requirement of iOS 4.2 to sync with the iPhone. This is a pretty embarrassing for Apple that they would release software reliant on other software before said software was released.
    Had I realised I was downloading a newer version at the initial point of installation, this wouldn't have been an issue. I could've easily have rolled back iTunes to the previous version and gotten on with my life.
    Another issue is that iTunes is not actually a 64 bit application. It masquerades as one to allow installation on the 64 bit platform.

  • Update to 10.7 did not work, cannot access iTunes. Need AVFoundationCF.dll, Ituneshelper not installed correctly, Error 7 (Windows Error 126), Error 7 (Windows Error 5)

    I am running Windows 7 64 bit.
    This HORROR  began because I realized that my phone had suddenly lost all of the music except music that had been purchased. It also lost all purchased iBooks as well as audible books downloaded from audible and ringtones that I had purchased from iTunes.
    I then thought that it would be fine once I connected to itunes on my computer. I connected to itunes and it said that there was an update available so I downloaded and installed 10.7.
    I tried to run the program and got Error 7 (Windows error 5) message.
    I then found several discussion questions that seemed similar to mine and I think that I tried them all. Removed everything apple and reinstalled iTunes. I followed the instructions and removed everything in the order that was listed, some I had to change security to own the file before I could delete them. I did all of the steps, (maybe I deleted too many apples items ??) emptied the recycling bin, restarted and reinstalled.  I also tried the Net framework fix, used the ms fixit (the one with the picture of the man on it) and I think a few other things that I have found on this site as well as MS site. I restarted my computer every time.
    The latest thing that I tried was to download 10.63 since I don't care about the new stuff.  After all of this I sometimes get and message saying that I am missing AVFoundationCF.dll file and once it said something about Itunes Helper (when these two messages appear, it is separate from the error messages which occur after clicking ok on them)  before getting the Error 7 (windows error 5) or else Error 7 (Windows error 126).
    PLEASE HELP!
