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