m4atag.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like m4atag.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 M4a to MP3 Converter) could share the same m4atag.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 m4atag.dll is attempted to be loaded either when Free M4a to MP3 Converter is starting up, or in some cases already running. Some of the most common m4atag.dll errors include:
- Access Violation at address - m4atag.dll.
- m4atag.dll could not be found.
- Cannot find C:\Program Files (x86)\Free M4a to MP3 Converter\m4atag.dll.
- Cannot register m4atag.dll.
- Cannot start Free M4a to MP3 Converter. A required component is missing: m4atag.dll. Please install Free M4a to MP3 Converter again.
- Failed to load m4atag.dll.
- The application has failed to start because m4atag.dll was not found.
- The file m4atag.dll is missing or corrupt.
- This application failed to start because m4atag.dll was not found. Re-installing the application may fix this problem.
Your m4atag.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Free M4a to MP3 Converter), or deleted by a malware infection. Furthermore, m4atag.dll file corruption could be caused from a power outage when loading Free M4a to MP3 Converter, system crash while loading m4atag.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.
