M4VConvert.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like M4VConvert.dll, 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. Wondershare UniConverter) could share the same M4VConvert.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 M4VConvert.dll is attempted to be loaded either when Wondershare UniConverter is starting up, or in some cases already running. Some of the most common M4VConvert.dll errors include:
- Access Violation at address - M4VConvert.dll.
- M4VConvert.dll could not be found.
- Cannot find C:\Program Files (x86)\Wondershare\Video Converter Ultimate\M4VConvert.dll.
- Cannot register M4VConvert.dll.
- Cannot start Wondershare UniConverter. A required component is missing: M4VConvert.dll. Please install Wondershare UniConverter again.
- Failed to load M4VConvert.dll.
- The application has failed to start because M4VConvert.dll was not found.
- The file M4VConvert.dll is missing or corrupt.
- This application failed to start because M4VConvert.dll was not found. Re-installing the application may fix this problem.
Your M4VConvert.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Wondershare UniConverter), or deleted by a malware infection. Furthermore, M4VConvert.dll file corruption could be caused from a power outage when loading Wondershare UniConverter, system crash while loading M4VConvert.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.
