How to Fix Xvidcore.dll Not Found or Missing Errors

Xvidcore.dll errors are caused by situations that lead to the removal or corruption of xvidcore.dll, a DLL file associated with the Xvid video codec library.

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

Xvidcore.dll Errors

There are several ways xvidcore.dll errors can show up on your computer. Here are some of the more common error messages you might see:

• Xvidcore.dll Not Found
• This application failed to start because xvidcore.dll was not found. Re-installing the application may fix this problem.
• Cannot find [PATH]\xvidcore.dll
• The file xvidcore.dll is missing.
• Cannot start [APPLICATION]. A required component is missing: xvidcore.dll. Please install [APPLICATION] again.

The context of the xvidcore.dll error is an important piece of information that will be helpful while solving the problem. These error messages might appear while using or installing certain programs or when Windows starts or shuts down.

For example, because Freemake Video Converter, Any Video Converter, MAGIX software, and Miro use this DLL file, you might see an xvidcore.dll error message when trying to edit, convert, or play a video file.

How to Fix Xvidcore.dll Errors

Follow these steps in the order they're given below to try the simpler solutions first.

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

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

   Start Windows in Safe Mode to complete any of these steps if you're unable to access Windows normally due to the error.

2. Download and install Xvid to put xvidcore.dll on your computer. This is the original source of the file, so it's entirely safe and even recommended to download xvidcore.dll here.

   Installing the Xvid software will put one xvidcore.dll file in each of these folders (or just the first one on some Windows installations):
   

   C:\Windows\System32\
   C:\Windows\SysWOW64\
   

   If you know where xvidcore.dll should be stored so that the program throwing the error can use it, try copying the file straight out of one of those folders and putting it wherever it needs to go.

3. Reinstall the program that uses the xvidcore.dll file if installing the Xvid codec didn't work. If the error occurs when you use a particular program, reinstalling the program should replace the file.

   Try your best to complete this step. Reinstalling the program that provides the xvidcore.dll file, if possible, is a likely solution to this DLL error.

4. Run a virus/malware scan of your entire system. Some xvidcore.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 error you're seeing is related to a hostile program that's masquerading as the file.

5. Update the drivers for hardware devices that might be related to xvidcore.dll. If, for example, you're receiving a "The file xvidcore.dll is missing" error when you play a 3D video game, try updating the drivers for your video card.

   The xvidcore.dll file may or may not be related to video cards—this was just an example. The key here is to pay very close attention to the context of the error and troubleshoot accordingly.

6. Roll back a driver to a previously installed version if xvidcore.dll errors began after updating a particular hardware device's driver.

7. 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 xvidcore.dll file could be included in one of those updates.

8. 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 xvidcore.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.

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

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

    We rarely recommend the use of registry cleaners. They're included as an option here as a "last resort" attempt before the destructive step coming up next.

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

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

12. Troubleshoot for a hardware problem if any xvidcore.dll errors persist. After a clean Windows installation, your DLL problem can only be hardware related.
