pthreadVC.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like pthreadVC.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like mighost.exe - to follow. These files were created so that multiple programs (eg. BlackWidow) could share the same pthreadVC.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 pthreadVC.dll is attempted to be loaded either when BlackWidow is starting up, or in some cases already running. Some of the most common pthreadVC.dll errors include:
- Access Violation at address - pthreadVC.dll.
- pthreadVC.dll could not be found.
- Cannot find C:\Windows\SysWOW64\pthreadVC.dll.
- Cannot register pthreadVC.dll.
- Cannot start BlackWidow. A required component is missing: pthreadVC.dll. Please install BlackWidow again.
- Failed to load pthreadVC.dll.
- The application has failed to start because pthreadVC.dll was not found.
- The file pthreadVC.dll is missing or corrupt.
- This application failed to start because pthreadVC.dll was not found. Re-installing the application may fix this problem.
Your pthreadVC.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with BlackWidow), or deleted by a malware infection. Furthermore, pthreadVC.dll file corruption could be caused from a power outage when loading BlackWidow, system crash while loading pthreadVC.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.
