What are x264vfw.dll Error Messages?


Dynamic Link Library x264vfw.dll Errors

x264vfw.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like x264vfw.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like mrt.exe - to follow. These files were created so that multiple programs (eg. Media Player Codec Pack) could share the same x264vfw.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 x264vfw.dll is attempted to be loaded either when Media Player Codec Pack is starting up, or in some cases already running. Some of the most common x264vfw.dll errors include:

Your x264vfw.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Media Player Codec Pack), or deleted by a malware infection. Furthermore, x264vfw.dll file corruption could be caused from a power outage when loading Media Player Codec Pack, system crash while loading x264vfw.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 x264vfw.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 x264vfw.dll issue. These troubleshooting steps are listed in the recommended order of execution.


Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

  1. Hit the Windows Start button

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many x264vfw.dll error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

  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 x264vfw.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 x264vfw.dll File (Caution: Advanced)

Download x264vfw.dll Files (Malware-Tested 100% Clean)


CAUTION : We strongly advise against downloading and copying x264vfw.dll to your appropriate Windows system directory. Media Player Codec Pack typically does not release Media Player Codec Pack 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 x264vfw.dll and all other DLL files for Media Player Codec Pack. An incorrectly installed DLL file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
