mpack401.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mpack401.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. Easy Video Splitter) could share the same mpack401.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 mpack401.dll is attempted to be loaded either when Easy Video Splitter is starting up, or in some cases already running. Some of the most common mpack401.dll errors include:
- Access Violation at address - mpack401.dll.
- mpack401.dll could not be found.
- Cannot find C:\Program Files (x86)\Easy Video Splitter\mpack401.dll.
- Cannot register mpack401.dll.
- Cannot start Easy Video Splitter. A required component is missing: mpack401.dll. Please install Easy Video Splitter again.
- Failed to load mpack401.dll.
- The application has failed to start because mpack401.dll was not found.
- The file mpack401.dll is missing or corrupt.
- This application failed to start because mpack401.dll was not found. Re-installing the application may fix this problem.
Your mpack401.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Easy Video Splitter), or deleted by a malware infection. Furthermore, mpack401.dll file corruption could be caused from a power outage when loading Easy Video Splitter, system crash while loading mpack401.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.
