vidonnav.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like vidonnav.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 7za.exe - to follow. These files were created so that multiple programs (eg. DVDFab) could share the same vidonnav.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 vidonnav.dll is attempted to be loaded either when DVDFab is starting up, or in some cases already running. Some of the most common vidonnav.dll errors include:
- Access Violation at address - vidonnav.dll.
- vidonnav.dll could not be found.
- Cannot find C:\Program Files (x86)\DVDFab Media Player 3\system\players\dvdplayer\vidonnav.dll.
- Cannot register vidonnav.dll.
- Cannot start DVDFab. A required component is missing: vidonnav.dll. Please install DVDFab again.
- Failed to load vidonnav.dll.
- The application has failed to start because vidonnav.dll was not found.
- The file vidonnav.dll is missing or corrupt.
- This application failed to start because vidonnav.dll was not found. Re-installing the application may fix this problem.
Your vidonnav.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with DVDFab), or deleted by a malware infection. Furthermore, vidonnav.dll file corruption could be caused from a power outage when loading DVDFab, system crash while loading vidonnav.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.
