DirectShowDemuxFilter.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like DirectShowDemuxFilter.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like AM_Delta.exe - to follow. These files were created so that multiple programs (eg. DivX) could share the same DirectShowDemuxFilter.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 DirectShowDemuxFilter.dll is attempted to be loaded either when DivX is starting up, or in some cases already running. Some of the most common DirectShowDemuxFilter.dll errors include:
- Access Violation at address - DirectShowDemuxFilter.dll.
- DirectShowDemuxFilter.dll could not be found.
- Cannot find C:\Program Files (x86)\DivX\Codecs\DirectShowDemuxFilter.dll.
- Cannot register DirectShowDemuxFilter.dll.
- Cannot start DivX. A required component is missing: DirectShowDemuxFilter.dll. Please install DivX again.
- Failed to load DirectShowDemuxFilter.dll.
- The application has failed to start because DirectShowDemuxFilter.dll was not found.
- The file DirectShowDemuxFilter.dll is missing or corrupt.
- This application failed to start because DirectShowDemuxFilter.dll was not found. Re-installing the application may fix this problem.
Your DirectShowDemuxFilter.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with DivX), or deleted by a malware infection. Furthermore, DirectShowDemuxFilter.dll file corruption could be caused from a power outage when loading DivX, system crash while loading DirectShowDemuxFilter.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.
