What are mmmpcdec.ax Error Messages?


Dynamic Link Library mmmpcdec.ax Errors

mmmpcdec.ax is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mmmpcdec.ax, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like memtest.exe - to follow. These files were created so that multiple programs (eg. Free Convert to DIVX AVI WMV MP4 MPEG Converter) could share the same mmmpcdec.ax 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 AX 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 mmmpcdec.ax is attempted to be loaded either when Free Convert to DIVX AVI WMV MP4 MPEG Converter is starting up, or in some cases already running. Some of the most common mmmpcdec.ax errors include:

Your mmmpcdec.ax file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Free Convert to DIVX AVI WMV MP4 MPEG Converter), or deleted by a malware infection. Furthermore, mmmpcdec.ax file corruption could be caused from a power outage when loading Free Convert to DIVX AVI WMV MP4 MPEG Converter, system crash while loading mmmpcdec.ax, 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.
