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