Fixing iTunes 11.1.4 – msvcr80.dll

Did you upgrade your iTunes this week to the latest version? Did the upgrade fail? If you’re running Windows 7 64-bit it seems there is a very good chance it did and corrupted some files during the install. Many people are reporting seeing a window pop up on boot saying “Cannot start [APPLICATION]. A required component is missing: msvcr80.dll. Please install [APPLICATION] again.”

This error seems to affect a good number of installations. In fact, 2 of the 3 computers I have iTunes installed on experienced a failed update. All are running Windows 7 64-bit. Oddly the two that failed were running the “Home” version, while the successful one was an “Ultimate” installation. I don’t know if that matters at this point, if you’ve read this far odds are good you’re looking for a solution. Good news, I’ve found a method that works and you won’t lose any of your iTunes data.

First, make sure you download a copy of the latest iTunes directly from Apple. It’ll be in your download folder (150+ MB) when it is finished. Go ahead and start the download and then continue.

We’re going to need to manually remove a couple Apple programs. Don’t worry, the new installation will put them back.

  • Go to your Start button and type “Remove” in the search bar.
  • Select “Add or remove programs” from the search list.
  • When the Control Panel box opens up, click on the “Publisher” tab to sort the programs.
  • Uninstall the following highlighted applications:

iTunes Uninstall PageYeah, that’s World of Warcraft on my list. Haven’t played it in a year, but don’t judge…

Oddly, the offending program seems to be “Apple Mobile Device Support”, but you will (should) not be able to uninstall it here. The uninstall starts and then reverts itself back on its own. We’ll need to tackle this one a bit differently.

  • Navigate to C:/Program Files (x86)/Common Files/Apple
  • Look for the folder names “Mobile Device Support” and delete it.

Apple Mobile Device Support LocationNotice how we didn’t touch iTunes at all (yet)?! If you try to open it, it won’t start. Now head to your download folder and double-click on itunes64setup.exe to begin the reinstallation of iTunes. Let it run its course and when finished you should be able to fire up iTunes as normal!
