What are libx264-148.dll Error Messages?

Dynamic Link Library libx264-148.dll Errors

Libx264-148.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libx264-148.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. FLV Downloader Pro) could share the same libx264-148.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 libx264-148.dll is attempted to be loaded either when FLV Downloader Pro is starting up, or in some cases already running. Some of the most common libx264-148.dll errors include:

Your libx264-148.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with FLV Downloader Pro), or deleted by a malware infection. Furthermore, libx264-148.dll file corruption could be caused from a power outage when loading FLV Downloader Pro, system crash while loading libx264-148.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.

  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 libx264-148.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 libx264-148.dll File (Caution: Advanced)
