Windows error 126 on home computer

when I click onto itunes on my windows home computer and error message pops up
MSVCR80.dll   windows error 126
tells me to re install itunes
however after 10 attemps yesterday that wouldn't work either.
How do I fix this?

You may have to follow the slightly more detailed steps in whichever of these two applies to you.
HT1925: Removing and Reinstalling iTunes for Windows XP
HT1923: Removing and reinstalling iTunes for Windows Vista, Windows 7, or Windows 8
Rebooting into safe mode may be needed to delete any folder the instructions say you should remove. You may also find this Microsoft Fixit helps to remove stubborn components. It has taken some people several attempts to completely clean iTunes and supporting software before they have been able to successfully reinstall it.

  • When I plug in my Ipod touch to my computer a warning appears "The program cant start because MSVCR80.dll is missing."  I can not access my Itunes library.  Also, an "error 7 Windows error 126" appears as well.  Any ideas?

    When I plug in my Ipod Touch to my computer I can not access my Itunes library.  The following message appears "The program cant start because MSVCR80.dll is missing."  Also, another message appears as well - "Error 7  Windows error 126" as well as APSDaemon.exe.
    I have NO IDEA what the heck to do.

    Troubleshooting issues with iTunes for Windows updates

  • After doing a suggested update of itunes on my pc it will not open and gives me a msg saying msvcr80.dll is not on my computer and windows error 126 has occured

    After doing an update of itunes on my pc Itunes will no longer open and gives me a msg about MSVCR80.dll not on my computer and Itunes was installed incorrectly error 7 (windows error 126)

    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.

  • "Error 7 (Windows error 126)" for Windows XP Home edition

    Hi,
    I have problems with installing iTunes correctly on my laptop.
    I get the following error-message when I try to open iTunes:
    "iTunes was not installed correctly. Please reinstall iTunes.
    Error 7 (Windows error 126)"
    Futhermore I get this error-message:
    "This program can't start, because AVFoundationCF.dll couldn't be found."
    I tried to install iTunes many times but nothing seems to work.
    Help, pleace?

    many thanks.
    "Titled: 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."\
    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. Now 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 it's 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):

    If the above doesn’t do the trick entirely, then use the instructions in the following as it applies to the version of Windows you are using:
    HT1925: Removing and Reinstalling iTunes for Windows XP
    HT1923: Removing and reinstalling iTunes for Windows Vista, Windows 7, or Windows 8
    You may be required to boot into safe mode to complete the folder deletion process.

    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

  • I clicked "yes" to upgrade iTunes and now it doesn't work. I get an error message stating my computer is missing MSVCR80 and then a message stating Error 7 (Windows Error 126). I've tried reloading iTunes twice. What can I do?

    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.

    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".

    Get message that Itunes can't start because MSVCR80.dll is missing from your computer - try reinstalling.
    When I reinstall I get Itunes is not installed correctly - plse reinstall - Error 7 (Windows error 126)

    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.
