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