What are avutil-lav-51.dll Error Messages?


Dynamic Link Library avutil-lav-51.dll Errors

avutil-lav-51.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like avutil-lav-51.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Windows 8 Codecs Pack) could share the same avutil-lav-51.dll file, saving valuable memory allocation, therefore making your computer run more efficiently.

Unfortunately, what makes DLL files so convenient and efficient, also makes them extremely vulnerable to problems. If something happens to a shared DLL file, either it goes missing or gets corrupted in some way, it can generate a "runtime" error message. Runtime is pretty self-explanatory; it means that these errors are triggered when avutil-lav-51.dll is attempted to be loaded either when Windows 8 Codecs Pack is starting up, or in some cases already running. Some of the most common avutil-lav-51.dll errors include:

Your avutil-lav-51.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Windows 8 Codecs Pack), or deleted by a malware infection. Furthermore, avutil-lav-51.dll file corruption could be caused from a power outage when loading Windows 8 Codecs Pack, system crash while loading avutil-lav-51.dll, bad sectors on your storage media (usually your primary hard drive), or quite commonly, a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.



How to Fix avutil-lav-51.dll Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your avutil-lav-51.dll issue. These troubleshooting steps are listed in the recommended order of execution.

  4. If updates are available for download, click "Install Updates".
  5. After the update is completed, restart your PC.

If Windows Update failed to resolve the avutil-lav-51.dll error message, please proceed to next step. Please note that this final step is recommended for advanced PC users only.



If Those Steps Fail: Download and Replace Your avutil-lav-51.dll File (Caution: Advanced)

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate avutil-lav-51.dll file version.
