What are mc_dec_aac_ds.ax Error Messages?

Dynamic Link Library mc_dec_aac_ds.ax Errors

mc_dec_aac_ds.ax is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mc_dec_aac_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_aac_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_aac_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_aac_ds.ax errors include:

Access Violation at address - mc_dec_aac_ds.ax.
mc_dec_aac_ds.ax could not be found.
Cannot find C:\Program Files (x86)\Research In Motion\BlackBerry Desktop\Codecs\mc_dec_aac_ds.ax.
Cannot register mc_dec_aac_ds.ax.
Cannot start BlackBerry Desktop Manager. A required component is missing: mc_dec_aac_ds.ax. Please install BlackBerry Desktop Manager again.
Failed to load mc_dec_aac_ds.ax.
The application has failed to start because mc_dec_aac_ds.ax was not found.
The file mc_dec_aac_ds.ax is missing or corrupt.
This application failed to start because mc_dec_aac_ds.ax was not found. Re-installing the application may fix this problem.

Your mc_dec_aac_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_aac_ds.ax file corruption could be caused from a power outage when loading BlackBerry Desktop Manager, system crash while loading mc_dec_aac_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.

Step 3: Perform a Windows Update.

Download mc_dec_aac_ds.ax Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying mc_dec_aac_ds.ax to your appropriate Windows system directory. BlackBerry typically does not release BlackBerry Desktop Manager AX 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 mc_dec_aac_ds.ax and all other AX files for BlackBerry Desktop Manager. An incorrectly installed AX file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
