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