Okay. Not an issue with a damaged AVFoundationCF.dll file either then, because the Apple Application Support has been swapped out.

Since upgrading iTunes around the 16th December (give or take a day or two) i have been unable to launch the program, constantly seeing the following message:

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?
Troubleshooting issues with iTunes for Windows updates -
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. -
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!Follow the instructions on this link, basically un-install everything, remove programs that says they are made by apple inc. (using add remove program)

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 -
I downloaded the latest version of iTunes on my PC. Now I cannot open iTunes. I receive the following error message: "The procedure entry point AVCFAssetCreateWithByteStreamAndOptions could not be located in the dynamic link library AVfoundationCF.dll" After pressing the "OK" button I receive a second error message: 'iTunes not installed correctly. Please reinstall iTunes. Error 7 (Windows error 127)". I've uninstalled iTunes and reinstalled to no avail. I've also eliminated the temp files (per suggestions on the trouble-shooting page) and no luck. I also tried system restore and that did not fix the problem. Any thougths on a repair?
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. 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 the procedure is for Vista and 7 and you've got XP, 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.)

I have Windows Vista computer. I am trying to upgrade my ITunes so can share files with other home computer. (Just got the new IPhone). I get this system error: The procedure entry point AVCFPlayerItemDurationChangedNotification could not be located in the dynamic link library AVFoundationCF.dll. Tries system restore and redownloaded...NOW Itunes will not even open. Can anyone help?
I uninstalled Apple Application Support, opened iTunesSetup with WinRar, and went down the list of msi's. AppleApplicationSupport was an install, all the others I did Repair. Did not have to reboot. Works okay now.

While running an update in itunes (not installing), it stopped in the middle of the update and i receceived the following messages:
Application failed to start because AVFoundationCF.dll was not found. Reinstalling itunes may fix the problem. Then "itunes was installed incorrectly. Please reinstall itunes Error 7 (Windows error 126)". If i uninstall and reinstall itunes will I lose all of my music, etc.?Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall press on)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

How do I fix this? Please helpIf I do the reinstall do I lose all the music I have loaded onto my computer?
In the normal course of events, an uninstall/reinstall doesn't touch your content files. (That being said, it's always a good idea to have a backup in case of disasters.)
On a Windows 7 machine, I'd try the instructions from the following post (given that the AAS repair didn't work for us):

I just tried updating to iTunes 10.7 and when I try to launch it I get this error message-The procedure entry point AVCFPlayerSetDirect3DDevice could not be located in the dynamic library AVFoundationCF.dll. Them it tells me to re-install iTunes and the same thing happens again. Any Ideas?
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.)
Re: I recently updated to vista service pack 2 and I updated to itunes 10.2.1 and ever -
I updated iTunes today (Windows). I restarted the computer but when I tried to launch, I get the message, ""The procedure entry point AVCFURLAssetInheritURIQueryComponentFromReferencingURIKey could not be located in the dynamic link library AVFoundationCF.dll".
I then did a new install of the latest iTunes version and got the same problem. No more iTunes.
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.

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.

Can't launch itunes due to the following error; The procedure entry point AVCFPlayerAppliesMediaSelectionCriteriaKey could not be located in the dynamic link library AVFoundationCF.dll.
Hey bcolden,
I would try uninstalling and reinstalling following the directions in here:
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
http://support.apple.com/kb/HT1923
This section in particular contains important information in the uninstall process:
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.
Let us know if following that article and uninstalling those components in that order helped the situation.
Welcome to Apple Support Communities!
Best,
