What are WLXMP4Parser.dll Error Messages?


Dynamic Link Library WLXMP4Parser.dll Errors

WLXMP4Parser.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like WLXMP4Parser.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 Live Essentials 2012) could share the same WLXMP4Parser.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 WLXMP4Parser.dll is attempted to be loaded either when Windows Live Essentials 2012 is starting up, or in some cases already running. Some of the most common WLXMP4Parser.dll errors include:

Your WLXMP4Parser.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Windows Live Essentials 2012), or deleted by a malware infection. Furthermore, WLXMP4Parser.dll file corruption could be caused from a power outage when loading Windows Live Essentials 2012, system crash while loading WLXMP4Parser.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.

  1. Hit the Windows Start button

Step 3: Perform a Windows Update.

  1. Hit the Windows Start button
  2. In the search box, type "Update" and press "ENTER".
  3. In the Windows Update dialog box, click "Check for Updates" (or similar button depending on your Windows version)
  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 WLXMP4Parser.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 WLXMP4Parser.dll File (Caution: Advanced)

Download WLXMP4Parser.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying WLXMP4Parser.dll to your appropriate Windows system directory. Microsoft typically does not release Windows Live Essentials 2012 DLL files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing WLXMP4Parser.dll and all other DLL files for Windows Live Essentials 2012. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
