out_WASAPI.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like out_WASAPI.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 4gb_patch.exe - to follow. These files were created so that multiple programs (eg. MediaMonkey) could share the same out_WASAPI.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 out_WASAPI.dll is attempted to be loaded either when MediaMonkey is starting up, or in some cases already running. Some of the most common out_WASAPI.dll errors include:
- Access Violation at address - out_WASAPI.dll.
- out_WASAPI.dll could not be found.
- Cannot find C:\Program Files (x86)\MediaMonkey\Plugins\out_WASAPI.dll.
- Cannot register out_WASAPI.dll.
- Cannot start MediaMonkey. A required component is missing: out_WASAPI.dll. Please install MediaMonkey again.
- Failed to load out_WASAPI.dll.
- The application has failed to start because out_WASAPI.dll was not found.
- The file out_WASAPI.dll is missing or corrupt.
- This application failed to start because out_WASAPI.dll was not found. Re-installing the application may fix this problem.
Your out_WASAPI.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with MediaMonkey), or deleted by a malware infection. Furthermore, out_WASAPI.dll file corruption could be caused from a power outage when loading MediaMonkey, system crash while loading out_WASAPI.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.
