What are MPG4DEMUX.dll Error Messages?


Dynamic Link Library MPG4DEMUX.dll Errors

MPG4DEMUX.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like MPG4DEMUX.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 MPG4DEMUX.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 MPG4DEMUX.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 MPG4DEMUX.dll errors include:

Your MPG4DEMUX.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, MPG4DEMUX.dll file corruption could be caused from a power outage when loading Windows Live Essentials 2012, system crash while loading MPG4DEMUX.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.
