What are mc_dec_mp4v_ds.ax Error Messages?


Dynamic Link Library mc_dec_mp4v_ds.ax Errors

mc_dec_mp4v_ds.ax is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mc_dec_mp4v_ds.ax, 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. BlackBerry Desktop Manager) could share the same mc_dec_mp4v_ds.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 mc_dec_mp4v_ds.ax is attempted to be loaded either when BlackBerry Desktop Manager is starting up, or in some cases already running. Some of the most common mc_dec_mp4v_ds.ax errors include:

Your mc_dec_mp4v_ds.ax file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with BlackBerry Desktop Manager), or deleted by a malware infection. Furthermore, mc_dec_mp4v_ds.ax file corruption could be caused from a power outage when loading BlackBerry Desktop Manager, system crash while loading mc_dec_mp4v_ds.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.
