mp4_enc.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mp4_enc.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like FileCoAuth.exe - to follow. These files were created so that multiple programs (eg. Free iPod Video Converter) could share the same mp4_enc.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 mp4_enc.dll is attempted to be loaded either when Free iPod Video Converter is starting up, or in some cases already running. Some of the most common mp4_enc.dll errors include:
- Access Violation at address - mp4_enc.dll.
- mp4_enc.dll could not be found.
- Cannot find C:\Program Files (x86)\Free iPod Video Converter\mp4_enc.dll.
- Cannot register mp4_enc.dll.
- Cannot start Free iPod Video Converter. A required component is missing: mp4_enc.dll. Please install Free iPod Video Converter again.
- Failed to load mp4_enc.dll.
- The application has failed to start because mp4_enc.dll was not found.
- The file mp4_enc.dll is missing or corrupt.
- This application failed to start because mp4_enc.dll was not found. Re-installing the application may fix this problem.
Your mp4_enc.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Free iPod Video Converter), or deleted by a malware infection. Furthermore, mp4_enc.dll file corruption could be caused from a power outage when loading Free iPod Video Converter, system crash while loading mp4_enc.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.
