Q: iTunes install errors: MSVCR80.dll and Error 7 (windows error 126)

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

    Perhaps the way you've rolled out iTunes up until now, and the history of past installs, affects the success. It might be worth putting a test in your script to check that all has removed cleanly before attempting the reinstall.

    Not sure that it matters but I fixed the order of operations to correspond to the order that Apple suggests in the KB articles and added the folder cleanup.  The folder cleanup stage hasn't been thoroughly tested yet but should work fine:

     

    @echo off

    echo Close outlook before proceeding

    Pause

     

    echo Unistalling iTunes 11.1.4.62

    MsiExec.exe /X{0D924CB2-2EA4-4044-BAF7-770202D6BD0D} /passive

     

    echo Uninstalling Apple Software Update 2.1.3.127

    MsiExec.exe /X{789A5B64-9DD9-4BA5-915A-F0FC0A1B7BFE} /passive

     

    echo Uninstalling Mobile Device Support 7.1.0.32

    MsiExec.exe /X{FE86CB0C-FCB3-4358-B4B0-B0A41E33B3DD} /passive

     

    echo Unistalling Bonjour 3.0.0.10

    MsiExec.exe /X{6E3610B2-430D-4EB0-81E3-2B57E8B9DE8D} /passive

     

    echo Uninstalling Apple Application Support 3.0

    MsiExec.exe /X{A922C4B7-50E0-4787-A94C-59DBF3C65DBE} /passive

     

    Echo Cleaning Up Folders

    rmdir /s /q "C:\Program Files\Bonjour\"

    rmdir /s /q "C:\Program Files (x86)\Bonjour\"

    rmdir /s /q "C:\Program Files\Common Files\Apple\"

    rmdir /s /q "C:\Program Files (x86)\Common Files\Apple\"

    rmdir /s /q "C:\Program Files\iTunes\"

    rmdir /s /q "C:\Program Files (x86)\iTunes\"

    rmdir /s /q "C:\Program Files\iPod\"

    rmdir /s /q "C:\Program Files (x86)\iPod\"

    I'm not certain either, though it would be significant if changing the order affects your success.

    THANK YOU! This appears to have worked. I'm not very computer savvy, just know the basics but your instructions were easy to follow.

    Yesterday I also tried to download the update for iTunes and everything stopped working. Same MSVCR80.dll and Error 7 messages.  Thanks for the tips - I also removed any extra still undeleted program files from the Apple folder on the C drive, re-booted and downloaded iTunes from scratch. I had, like others on this site, spent nearly a day trying to sort out the problem so I'm really grateful for the helpful hints.  Everything working fine and all my music still there!

    I have also encountered this problem. So as mentioned, i removed all Apple programs and then reinstalled iTunes and it's up and running fine now. However, my library and playlists have gone.

     

    I think i know why this has happened... I renamed the iTunes folder to "iTunes 1" as someone advised doing so that i could see if there was any change or not and what it has done is created a 2nd iTunes folder as part of the fresh installation process. So i merged these folders together and then opened iTunes and it's not bringing up my library and playlists, it just wants to start from fresh.

     

    Any idea what i can do? The files must still be there as it's only created duplicates.

    When you merged the two folders the "newer" empty library probably took precedence over the older, larger one. Did you tell Windows to keep both copies, or is the original still in the iTunes 1 folder? Take a look at Empty/corrupt iTunes library after upgrade/crash. If you have managed to delete the working copy of your database then you can restore an older version and bring it up to date with the contents of the media folder.

    That's done the trick. Turns out it duplicated the iTunes library file and renamed the old file to "iTunesLibrary.itl (2)" therefore not recognizing this file primarily. All i had to do was delete the latest and newly created file (today's date) and rename the file from 2 days ago to "ITunesLibray.itl"

     

    Thanks you so much!

    Yep, or just don't rename any files/folders when reinstalling iTunes!

    It is appalling that Apple should release such a poor update.  It is quite shameful  and such a big company with stacks of technical staff.

    After doing what Apple suggested, now iTunes does not recognize my iPhone. It will charge while plugged but the iPhone button would not come on. Is that also a know issue?
