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