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

Followed cnet direct. to move itunes from c drive to ext. drive, worked, deleted off c, still worked, now says AVFoundationCF.dll not found-reinstall, don't want to lose data

I recently followed cnet directions to move itunes from c drive on pc running xp pro, to external drive, for space reasons. Process worked. I tunes ran from e drive, verified data on e drive, deleted all apple applications on c drive so I could remove itunes and recover space. Verified itunes still worked off of new short cut and and that target was e drive. Now itunes won't open and get message "AVFoundationCF.dll not found - reinstall", or "not installed correctly Error 7 (windows error 126) - reinstall." Tried download, install from apple.com for itunes on c drive, but message "library can't be read because it was created by a newer version of itunes." How do I fix this without losing all of our "material" saved on the itunes program?

Thank you for the reply, but so far no go. I tried through control panel and add remove programs with repair option as suggested but got error..."C:\programs......AppleAplicationSupport.msi cannot be found." This was after I have done new download and install of itunes to the c drive. I have not taken any steps to try use that down load or reload any material on it. I changed path to external drive an folder, E:\ itunes and got the "error not valid installation package." Still looking for answers...

Avfoundationcf.dll "Not Found" [FIX]

I discovered how to fix the problem of "avfoundationcf.dll Not Found" in windows xp 32 bit
You just need to Uninstall and Re-Install the 'AppleApplicationSupport"
Just go to this directory "C:\Documents and Settings\All Users\Application Data\Apple\Installer Cache\" and chose the directory "AppleApplicationSupport" with the higher version, my directory is "AppleApplicationSupport 2.1.6" Inside of this directory just run "AppleApplicationSupport.msi" and chose "Remove" when it finish run this file again and chose "Install"
It worked for me
Hope it help :]

This procedure might work or might not work:
Download the free Ccleaner and repair your Registry (repeat until clear)
http://www.piriform.com/ccleaner/download/standard
Uninstall iTunes according to Apple's directions here
http://support.apple.com/kb/HT1925
Use Ccleaner and repair your Registry again just in case.
Then download/install iTunes again from the Apple website
http://www.apple.com/itunes/
Your iTunes content will not be removed,
Please regularly backup your iTunes content to external medium (hard drive, cd/dvd's) using the File>Backup Library in iTunes. Apple will not reissue new copies of content.
(Notice: this post is a copy/paste in a hope that a uninstall/reinstall and repair of your Registry may solve your particular issue, Windows issues are particular difficult to resolve due to multiple factors, so my advice is to be taken into advisement with others recommendations which may be more specific or experienced in resolving your issue.

AVFoundationCF.dll not found? + Error 7 (Windows error 126)

About a week ago, I decided to upgrade to the newest version of iTunes. Upon trying to install the new version, it said it could not download as there was an error with quicktime. I then uninstallled and downloaded the newest version of Quicktime. The error message went away, however, now I am faced with this meassage everytime I attempt to install:
"An error occured during the assembly 'Microsoft.VC80.CRT,version="8.0.50727.4053"type="win32",publicKeyToken="1fc8b3 b9a1e18e3b",processorArchitecture="x86" Please Refer to Help and Support for more information HRESULT: 0x80073712
Then iTunes goes into "rolling back action" and 'completes' the install.
upon opening itunes, i get an error message saying that windows error 126 has occured or error 7, and that i should reinstall itunes. except i've done this six times now, so it clearly doesn't help.
supposedly the component AVFoundationCF.dll is not found, and the solution to that is REINSTALL, again, that doens't work.
What can I do?

Had this problem when I tried to upgrade. I eventually uninstalled all iTunes v9 related products (iTunes, Quicktime, Apple Application Support and Apple Software Update). Then I tried a fresh install of the v10.1x setup. I get the following:
Pop up#1 (iTunes.exe - Unable to Locate Component):
This application has failed to start because AVFoundationCF.dll was not found. Re-installing the application may fix this problem.
Pop up#2 (iTunes):
iTunes was not installed correctly. Please reinstall iTunes.
Error 7 (Windows error 126)
Since I'm on XP SP3 Home Edition, I can't install the System Readiness Tool (only for Vista, 7 and Server 2008, etc.).
So I gave up and unintalled all Apple products (iTunes, Quicktime, AAS, AMDS, ASU). I then went back to an iTunes 9.0.2 installsetup.exe I have. Installed "successfully" and now when I launch iTunes I get the following error pop up:
Pop up#3:
The file "iTunes Library.itl" cannot be read because it was created by a newer version of iTunes.
What can be done now? I'd like to be on the current version, but I can't get around the first 2 pop ups with the methods I've seen posted here.

Although you're getting a different error message, try the procedure from the following user tip with that one:

TS1717 Getting two error messages when trying to access I Tunes on my Windows 7 Computer: Windows Error 126 and MSVCR80.dll not found

Having difficulty accessing I Tunes on my Windows 7 Vista.
Error messages are two fold:
1. MSVCR80.dll not found. Reinstall may help correct prob.
2. Windows Error 126.

Uninstall your existing copy of iTunes. Delete any copies of the iTunesSetup.exe (or iTunes64Setup.exe) installer files from your downloads areas for your web browsers and download a fresh copy of the iTunes installer from the Apple website:
http://www.apple.com/itunes/download/
(The current build of the 11.1.4.62 installer was changed a few days ago, which fixed the bulk of the reports of MSVCR80.dll/R6034/APSDaemon.exe/Error-7/AMDS-could-not-start trouble ... but the build number on the installer was not changed. So we're trying to make sure you do the reinstall using a "new good" 11.1.4.62 installer instead of an "old bad".)
Does the install with the new copy of the installer go through properly? If so, does that clear up the error message?
If you still have the same error messages cropping up, then try the procedures from the following user tip:

Error messages - DDE Server Windows itunes.exe - Entry point Not found and iTunesHelper.exe - The procedure entry point asl_add_log_file could not be located in the dynamic link Library ASL.dll

Hi
I have tried to research these problems I am getting, but have not been able to resolve them.
1st is the above DDE Server Windows iTunes.exe - entry point not found.
This only occurs when I try to start iTunes.
if I click ok , several times, iTunes will start but slowly.
If at any time I have to reboot my computer I get
iTunesHelper.exe - the procedure entry point asl_add_log_file could not be located in the dynamic link library ASL.dll
if I click 3 times OK it goes away.
To this end I have uninstalled iTunes and rebooted my machine then gone to iTunes web site and downloaded the latest version.
Installing it but still get the same errors on reboot and trying to run iTunes
Anyone any ideas please.
I have a self build PC it has an Intel core 2 quad Q6000 @ 2.40GHz
Ram 4.00GB
32bit OS
Windows 7 Ultimate SP1
Firewall - Zonealarm
Virus - Zonealarm
Thanks in advance
Steve

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.)

My operating system is Windows XP SP3. I have Adobe 11.0.08 installed. I cannot print a pdf file/document. Error message - AeroRd32.exe - Unable To Locate Component - "Application failed to start because lxdautil.dll not found." Any suggestions?

That DLL is part of your printer driver; reinstall or update the device driver for your printer, and the message should go away.

Deleting itunes and reinstalling does not fix it.
