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