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