Dynamic Link Library libmfxsw32.dll Errors

libmfxsw32.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like libmfxsw32.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. AVS Video Editor) could share the same libmfxsw32.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 libmfxsw32.dll is attempted to be loaded either when AVS Video Editor is starting up, or in some cases already running. Some of the most common libmfxsw32.dll errors include:

• Access Violation at address - libmfxsw32.dll.
• libmfxsw32.dll could not be found.
• Cannot find C:\Program Files (x86)\AVS4YOU\AVSVideoEditor\libmfxsw32.dll.
• Cannot register libmfxsw32.dll.
• Cannot start AVS Video Editor. A required component is missing: libmfxsw32.dll. Please install AVS Video Editor again.
• Failed to load libmfxsw32.dll.
• The application has failed to start because libmfxsw32.dll was not found.
• The file libmfxsw32.dll is missing or corrupt.
• This application failed to start because libmfxsw32.dll was not found. Re-installing the application may fix this problem.

Your libmfxsw32.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with AVS Video Editor), or deleted by a malware infection. Furthermore, libmfxsw32.dll file corruption could be caused from a power outage when loading AVS Video Editor, system crash while loading libmfxsw32.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.
