avdevice-52.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like avdevice-52.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. MP3 Free Downloader) could share the same avdevice-52.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 avdevice-52.dll is attempted to be loaded either when MP3 Free Downloader is starting up, or in some cases already running. Some of the most common avdevice-52.dll errors include:
- Access Violation at address - avdevice-52.dll.
- avdevice-52.dll could not be found.
- Cannot find C:\Program Files (x86)\MP3FreeDownloader\avdevice-52.dll.
- Cannot register avdevice-52.dll.
- Cannot start MP3 Free Downloader. A required component is missing: avdevice-52.dll. Please install MP3 Free Downloader again.
- Failed to load avdevice-52.dll.
- The application has failed to start because avdevice-52.dll was not found.
- The file avdevice-52.dll is missing or corrupt.
- This application failed to start because avdevice-52.dll was not found. Re-installing the application may fix this problem.
Your avdevice-52.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with MP3 Free Downloader), or deleted by a malware infection. Furthermore, avdevice-52.dll file corruption could be caused from a power outage when loading MP3 Free Downloader, system crash while loading avdevice-52.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.
