vqdll.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like vqdll.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like dpnsvr.exe - to follow. These files were created so that multiple programs (eg. IGI 2: Covert Strike Single-player demo) could share the same vqdll.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 vqdll.dll is attempted to be loaded either when IGI 2: Covert Strike Single-player demo is starting up, or in some cases already running. Some of the most common vqdll.dll errors include:
- Access Violation at address - vqdll.dll.
- vqdll.dll could not be found.
- Cannot find C:\Program Files (x86)\Codemasters\IGI 2 Demo\pc\vqdll.dll.
- Cannot register vqdll.dll.
- Cannot start IGI 2: Covert Strike Single-player demo. A required component is missing: vqdll.dll. Please install IGI 2: Covert Strike Single-player demo again.
- Failed to load vqdll.dll.
- The application has failed to start because vqdll.dll was not found.
- The file vqdll.dll is missing or corrupt.
- This application failed to start because vqdll.dll was not found. Re-installing the application may fix this problem.
Your vqdll.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with IGI 2: Covert Strike Single-player demo), or deleted by a malware infection. Furthermore, vqdll.dll file corruption could be caused from a power outage when loading IGI 2: Covert Strike Single-player demo, system crash while loading vqdll.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.
