The context of the msvcr80.dll error is an important piece of information that will be helpful while solving the problem.

Cause of Msvcr80.dll Errors

Msvcr80.dll errors are caused by situations that lead to the removal or corruption of the msvcr80 DLL file.

In some cases, msvcr80.dll errors could indicate a registry problem, a virus or malware issue or even a hardware failure.

How To Fix Msvcr80.dll Errors

Important: Do not download msvcr80.dll from a "DLL download" website. There are many reasons why downloading a DLL file is a bad idea. If you need a copy of msvcr80.dll, it's best to obtain it from its original, legitimate source.

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.

  1. If, and only if, you're receiving the msvcr80.dll is missing error when you open Apple iTunes, do the following: (move on to Step 2 if your msvcr80.dll error is occurring with a different program)

    • Uninstall from Windows the following programs in this order: iTunes, Apple Software Update, Apple Mobile Device Support, Bonjour, Apple Application Support, iCloud, and finally MobileMe.

      Skip over any you don't have installed. If two entries are listed for a program, like Apple Mobile Device Support for example, uninstall the oldest one first, then the newer.

      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.
       
    • Restart your computer.
       
    • A proper iTunes uninstall, which you did in the first bullet point above, should have removed all Apple related software (not music, etc.) from your PC. However, if you suspect it didn't for some reason, like if you got some sort of error, you can finish the job yourself.

      To do so, manually delete the following four folders if they exist after Windows starts back up. Skip this if things seem to be going fine so far:
       
      • C:\Program Files\Bonjour
      • C:\Program Files\Common Files\Apple (just the Apple folder)
      • C:\Program Files\iPod
      • C:\Program Files\iTunes
      Note: In 64-bit versions of Windows, all of these folders will be inside a Program Files (x86) folder instead. Also, if Windows happens to be installed on a drive other than C on your computer (not common), look there instead.
       
    • Download the latest version of iTunes from Apple and note the location you're saving it to so you can find it once it's done downloading.
       
    • Run the iTunes installation as an administrator. Usually this involves right-clicking on the installation program and choosing Run as administrator. If you're having trouble with this, 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 helpful for running anything that way, 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.

      Important: If the above steps didn't work, or you're not seeing this problem with iTunes, move on to Step 2 below, which involves reinstalling the original source of the msvcr80.dll file.
  2. Download the Microsoft Visual C++ 2005 Service Pack 1 Redistributable Package MFC Security Update and run it. This will replace/restore the msvcr80.dll with the most recent copy provided by Microsoft.

    You're given several download options from Microsoft for this update, based on the version of Windows you have installed - x86 (32-bit) or x64 (64-bit). See Am I Running a 32-bit or 64-bit Version of Windows? for help if you're not sure what to choose.

    Important: Try your best to complete this step. Applying this update is almost always the solution to msvcr80.dll errors.

  3. Restore msvcr80.dll from the Recycle Bin. The easiest possible cause of a "missing" msvcr80.dll file is that you've mistakenly deleted it.

    If you suspect that you've accidentally deleted msvcr80.dll but you've already emptied the Recycle Bin, you may be able to recover msvcr80.dll with a free file recovery program.

    Important: Recovering a deleted copy of msvcr80.dll with a file recovery program is a smart idea only if you're confident you've deleted the file yourself and that it was working properly before you did that.

  4. Run a virus/malware scan of your entire system. Some msvcr80.dll errors could be related to a virus or other malware infection on your computer that has damaged the DLL file. It's even possible that the msvcr80.dll error you're seeing is related to a hostile program that's masquerading as the file.

  5. Use System Restore to undo recent system changes. If you suspect that the msvcr80.dll error was caused by a change made to an important file or configuration, a System Restore could solve the problem.

  6. Install any available Windows updates. Many service packs and other patches replace or update some of the hundreds of Microsoft distributed DLL files on your computer. The msvcr80.dll file could be included in one of those updates.

  7. Test your memory and then test your hard drive. I've left the majority of hardware troubleshooting to the last step, but your computer's memory and hard drive are easy to test and are the most likely components that might cause msvcr80.dll errors as they fail.

    If the hardware fails any of your tests, replace the memory or replace the hard drive as soon as possible.

  8. Repair your installation of Windows. If the individual msvcr80.dll file troubleshooting advice above is unsuccessful, performing a startup repair or repair installation should restore all Windows DLL files to their working versions.

  9. Use a free registry cleaner to repair msvcr80.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid msvcr80.dll registry entries that might be causing the DLL error.

    Important: I rarely recommend the use of registry cleaners. I've included the option here as a "last resort" attempt before the destructive step coming up next.

  10. Perform a clean installation of Windows. A clean install of Windows will erase everything from the hard drive and install a fresh copy of Windows. If none of the steps above correct the msvcr80.dll error, this should be your next course of action.

    Important: All the information on your hard drive will be erased during a clean install. Make sure you've made the best attempt possible to fix the msvcr80.dll error using a troubleshooting step prior to this one.

  11. Troubleshoot for a hardware problem if any msvcr80.dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related.

Applies To

The msvcr80.dll error message could apply to any program or system that might utilize the file on any of Microsoft's operating systems including Windows 8, Windows 7, Windows Vista, Windows XP, and Windows 2000.
