MSVCR80.dll is missing from your computer.

System Info: Windows 7 Home Premium, Service Pack 1


Help! This morning I tried opening my iTunes and received the error message "MSVCR80.dll is missing from your computer". I've tried repairing the program through windows control panel and still received message. Then, I deleted iTunes and tried to reinstall program. The upload would then hang up (something about mobile devices??), and would not install further. I had to cancel download, and tried to reinstall. Same result. 3rd step I tried was to install older version of iTunes. This was a success as far as the download, but then as I try opening, the same initial error "MSVCR80...." occured. Anyone out there having this problem?

Windows 7, iTunes

Hello ahab1964,


Thank you for the details of the issue you are experiencing with installing the latest iTunes update. I recommend following the steps below:


Resolution

Follow these steps to resolve the issue:

Check for .dll files

  1. Go to C:\Program Files (x86)\iTunes and C:\Program Files\iTunes and look for .dll files.
  2. If you find QTMovie.DLL, or any other .dll files, move them to the desktop.
  3. Reboot your computer.
    Note: Depending on your operating system, you may only have one of the listed paths.

Uninstall and reinstall iTunes

  1. Uninstall iTunes and all of its related components.
  2. Reboot your computer. If you can't uninstall a piece of Apple software, try using the Microsoft Program Install and Uninstall Utility.
  3. Re-download and reinstall iTunes 11.1.4.


I understand that you have already uninstalled iTunes, but when you get to this step, it is important to uninstall iTunes and the related components in the order listed in the link for that step.

Hi Sheila,


I appreciate your getting back with me and sending the instructions as to what to do. Unfortunately, I'm still having trouble getting iTunes to load on my computer. Here's what I've done up to now:


After searching all files in the iTunes folders ending with .dll, I moved all of these files to my desktop and then rebooted my computer. Next, I used the Window's Fixit Program to remove any remainder file fragments that may have been left on the harddrive during the uninstall of the previous iTunes. Then I rebooted my computer.


Next, I clicked the provided link (http://www.apple.com/itunes/download/) to download iTunes 11.1.4 for Window's (64-bit). While the download was progressing, an error message window popped up: "Service Apple Mobile Device failed to start. Verify that you have sufficent priviliges to start system services."

I looked at the troubleshooting article provided in your email, and found the services to the Apple Mobile Device and (1st) stopped the service, then (2nd) restarted the service. I tried to reinstall the iTunes download and received the same message as posted above, which leaves me back to square one. What do I do from here?

I finally was able to install iTunes!!


When unistalling Apple's software on my PC, I had to unstall all program files, yet one file, Apple Mobile Device Support, would not uninstall until I had unistalled every other Apple related program. After 2 hours of figuring out what to do (Quicktime was the last one - I had forgotton about it), THEN I was able to do an unistall of AMDS.


If you are having trouble getting rid of AMDS, unistall all Apple related software first, including:


  • iTunes
  • Apple Software Update
  • Bonjour
  • Apple Application Support
  • Safari
  • Quicktime
  • then, Apple Mobile Device Support


That's all there was to it, but wow, what an ordeal!!
