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.

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.

Hello Charleen,
It sounds like you are unable to reinstall iTunes because of this error message 7. I recommend the troublehsooting found in the following article that mentions that error named:
iTunes 11.1.4 for Windows: Unable to install or open
http://support.apple.com/kb/TS5376
"iTunes was not installed correctly. Please reinstall iTunes. Error 7 (Windows Error 126)”
Follow these steps to resolve the issue:
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.
Thank you for using Apple Support Communities.
Take care,
Sterling

Read the user tip: https://discussions.apple.com/docs/DOC-6562 for the most thorough explanation of fixing this problem.

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.

I keep getting this error message when i try to install the latest version of itunes, the program can't start because MSVCR80.dll is missing from your computer. try reinstalling the program to fix this problem??

I am having trouble reinstalling my Itunes on my desktop which uses Windows 7 and I can download it but once it's complete i keep getting this error message...The program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem. Please help me.

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.

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

I have the exact same problem.
I have uninstalled the program, rebooted and downloaded the update again. Same problem, same message.
Please, where is that missing MSVCR80.dll? I don't remember misplacing it.
I'm a Windows 7 user.

Can't download itunes update. Keep getting this error message: THe program can't start because MSVCR80.dll is missing from your computer. Try reinstalling the program to fix this problem

I researched the advice on the link provided by b noir as well as very similar advice from apple support: http://support.apple.com/kb/TS5376. It worked for me (for now).
Some things of note:
I did all of the things requested by the link I provided
My computer WOULD NOT uninstall Apple Mobile Device Support. I had to manually remove the folder (also as instructed by the url)
I also uninstalled MobileMe. Was a little different than removing the other apps. Follow instructs provided here: http://support.apple.com/kb/HT2992
I did not uninstall iCloud
I have to admit it was a bit scary removing all those things. Is important to note that when re-installing Apple, follow steps to do so as Administrator (the right-click thingy and whatnot).
Hope this helps!

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.
