mslvideocodecs4.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mslvideocodecs4.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like OneDriveSetup.exe - to follow. These files were created so that multiple programs (eg. VSDC Free Video Editor) could share the same mslvideocodecs4.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 mslvideocodecs4.dll is attempted to be loaded either when VSDC Free Video Editor is starting up, or in some cases already running. Some of the most common mslvideocodecs4.dll errors include:
- Access Violation at address - mslvideocodecs4.dll.
- mslvideocodecs4.dll could not be found.
- Cannot find C:\Program Files\Common Files\FlashIntegro\ActiveX\mslvideocodecs4.dll.
- Cannot register mslvideocodecs4.dll.
- Cannot start VSDC Free Video Editor. A required component is missing: mslvideocodecs4.dll. Please install VSDC Free Video Editor again.
- Failed to load mslvideocodecs4.dll.
- The application has failed to start because mslvideocodecs4.dll was not found.
- The file mslvideocodecs4.dll is missing or corrupt.
- This application failed to start because mslvideocodecs4.dll was not found. Re-installing the application may fix this problem.
Your mslvideocodecs4.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with VSDC Free Video Editor), or deleted by a malware infection. Furthermore, mslvideocodecs4.dll file corruption could be caused from a power outage when loading VSDC Free Video Editor, system crash while loading mslvideocodecs4.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.
