vegmuxfc.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like vegmuxfc.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. Sony Movie Studio 13) could share the same vegmuxfc.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 vegmuxfc.dll is attempted to be loaded either when Sony Movie Studio 13 is starting up, or in some cases already running. Some of the most common vegmuxfc.dll errors include:
- Access Violation at address - vegmuxfc.dll.
- vegmuxfc.dll could not be found.
- Cannot find C:\Program Files (x86)\Sony\Movie Studio 13.0\bdmux\vegmuxfc.dll.
- Cannot register vegmuxfc.dll.
- Cannot start Sony Movie Studio 13. A required component is missing: vegmuxfc.dll. Please install Sony Movie Studio 13 again.
- Failed to load vegmuxfc.dll.
- The application has failed to start because vegmuxfc.dll was not found.
- The file vegmuxfc.dll is missing or corrupt.
- This application failed to start because vegmuxfc.dll was not found. Re-installing the application may fix this problem.
Your vegmuxfc.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Sony Movie Studio 13), or deleted by a malware infection. Furthermore, vegmuxfc.dll file corruption could be caused from a power outage when loading Sony Movie Studio 13, system crash while loading vegmuxfc.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.
