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

Opening iTunes shows an error- The program can't start because AVFoundationCF.dll is missing from your computer. Try reinstalling the program to fix this problem. ; Even after reinstalling iTunes doesn't start!

"The program can't start because AVFoundationCF.dll is missing from your computer. Try reinstalling the program to fix this problem."
Even after reinstalling iTunes doesn't start!

Repair your Apple Application Support.
Control Panel > Programs n Features (Win7) or Add n Remove Programs(XP) > highlight AAS, click CHANGE then REPAIR.

TS1717 Started a software update this morning which didn't work. Now Itunes will not open at all. I get the following message."The program can't state becasue MSVCR80.dll is missing from your computer."

Started a Itunes software update this morning which didn't work. Now Itunes will not open at all. I get the following message."The program can't state becasue MSVCR80.dll is missing from your computer."

There are a couple of options that I know of to fix the issue.
One is listed in this thread - https://discussions.apple.com/message/24606478#24606478 - and involves uninstalling iTunes and related components and then re-installing iTunes. You will need to read the instructions in the thread to see the correct uninstall order.
Second option is use System Restore to set your system back to a date prior to the iTunes update. I did this before finding the thread mentioned above.
Not sure exactly what the problem is but I know, after a search, that MSVCR80.dll was indeed already installed on my computer.

TS5376 iTunes wont install. It says " The program can't start because MediaAccessibility.dll is missing from your computer. Try reinstalling the program to fix this problem." I have uninstalled iTunes 5 times and reinstalled it, and nothing has worked.

Click here and follow the instructions. You may need to completely remove and reinstall iTunes and all related components, or run the process multiple times; this won't normally affect its library, but that should be backed up anyway.

I am trying to install the newest version of Itunes and it fails with the message "Program cannot start MSVCR80.dll is missing from your computer. Try reinstalling program to fix this program.I have tried reinstalling several times but get same results

I am trying to install the newest version of Itunes and each time I repeatedly get the message "Program cannot start MSVCR80.dll is missing from your computer Try reinstalling to fix this problem". I have tried reinstalling several times and I get the same message . Any ideas? I am most appreciative. I am using Windows 7.

Hi 49balf,
Thanks for visiting Apple Support Communities.
I recommend removing and reinstalling iTunes using these steps:
Check for .dll files
Go to C:\Program Files (x86)\iTunes and C:\Program Files\iTunes and look for .dll files.
If you find QTMovie.DLL, or any other .dll files, move them to the desktop.
Reboot your computer.
Note: Depending on your operating system, you may only have one of the listed paths.
Uninstall and reinstall iTunes
Uninstall iTunes and all of its related components.
Reboot your computer. If you can't uninstall a piece of Apple software, try using the Microsoft Program Install and Uninstall Utility.
Re-download and reinstall iTunes 11.1.4.
You can find the article with these steps and more information here:

HT201210 After downloading latest version of iTunes it will not open. This error message is displayed; The program can't star because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem. Then a second error box

After iTunes requested that I download latest version on PC it now will not open. 2 error messages appear. first: The program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem. second: iTunes was not installed correctly please reinstall iTunes. Error 7 (Windows error 126). I have tried reinstalling a number of times and restarting computer but no luck.

This happened to me today as well post installing the latest version of itunes. I did a search on google for the error and came across a recommendation to :
Note: Start Windows in Safe Mode to complete any of the following steps if you're unable to access Windows normally due to the msvcr80.dll error.
If, and only if, you're receiving the msvcr80.dll is missing error when you open Apple iTunes, do the following: (skip this step if your msvcr80.dll error is occurring with a different program)
Uninstall from Windows the following five programs in this order: iTunes, Apple Software Update, Apple Mobile Device Support, Bonjour, and finally Apple Application Support. If you have iCloud, remove it as well.
Uninstalling these programs in Windows is done from an applet in Control Panel called Programs & Features (in Windows 8, 7, or Vista) or Add or Remove Programs (in Windows XP).
Note: Songs and playlists in iTunes will not be removed when you uninstall the iTunes program or any of the other, already-mentioned Apple programs. If you'd still like to back them up, they're usually located in the My Music folder in Windows.
Download the latest version of iTunes from Appleand note the location you're saving it to so you can find it once it's done.
Run the iTunes installation as an administrator. If you're not sure how to do that, see How Do I Open an Elevated Command Prompt? for help. That procedure shows you how to open the Command Prompt program as an administrator, but the steps are essentially the same for anything, including the iTunes installation package you just downloaded.
A general overview of removing and reinstalling iTunes can also be found here on Apple's site but the above procedure seems to work better in this particular situation.

My Itunes won't open. When I click on it I get error message: The program can't start because MSVCR80.dll is missing from your computer.

The first error message is: itunes.exe-System Error: the program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix the problem.
The second error message says: itunes: itunes was not installed correctly. Please reinstall itunes Error 7 (Windows error 126)
I have reinstalled several times and the same thing keeps happening. Does anyone know what to do?

Ralph, both links you've posted point to the same place!
Ah, I see the second one is meant to lead to Tony's tip: https://discussions.apple.com/docs/DOC-6571
That one applies for certain launch errors that can occur when iTunes has otherwise installed successfully. I've addressed the same issue in the first box of my tip.
What would be interesting to know is if Aswim does indeed have QTMovieWin.dll in their Program Files\iTunes folder, and if removing it allows iTunes to launch? It would seem that different error messages may be thrown up by different versions of the file on different versions of the OS. Perhaps many more people have been doing a complete rebuild than needed to.

Problem installing iTunes update: "Can't start" iTunes "because MSVCR80.dll is missing" from my computer. Please help!

Please help! I tried to update my iTunes as prompted, but it did not install correctly, and now I am getting the following message and do not know how to fix the problem:
"The program can't start because MSVCR80.dll is missing from your computer. Try reinstalling this program to fix the problem."
Another window gives me this message:
"iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 126)"
BUT I AM AFRAID TO REINSTALL iTUNES and lose my library! Would greatly appreciate learning how to resolve this porblem without losing my music!
Cheers!

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 move on to the next item)
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.

All of a sudden my iTunes stopped working, and I get the following error messages: 1. the program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem and 2. iTunes was not installed correct

All of a sudden my iTunes stopped working, and I get the following error messages:
1. the program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem
and
2. iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows error 126).
Now I've checked the forums and followed the advice of uninstalling all Apple applications, rebooting, and reinstalling iTunes.
This is not working. I've tried installing as Administrator but doesn't make any difference at all.
There must be a way to fix this? I'm not a tech geek but I want to avoid having to take my laptop back to factory settings to sort this out.
Thanks
