AuApplication.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like AuApplication.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 7za.exe - to follow. These files were created so that multiple programs (eg. Adobe Audition CS6) could share the same AuApplication.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 AuApplication.dll is attempted to be loaded either when Adobe Audition CS6 is starting up, or in some cases already running. Some of the most common AuApplication.dll errors include:
- Access Violation at address - AuApplication.dll.
- AuApplication.dll could not be found.
- Cannot find C:\Program Files\Adobe\Adobe Audition CC 2019\AuApplication.dll.
- Cannot register AuApplication.dll.
- Cannot start Adobe Audition CS6. A required component is missing: AuApplication.dll. Please install Adobe Audition CS6 again.
- Failed to load AuApplication.dll.
- The application has failed to start because AuApplication.dll was not found.
- The file AuApplication.dll is missing or corrupt.
- This application failed to start because AuApplication.dll was not found. Re-installing the application may fix this problem.
Your AuApplication.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Adobe Audition CS6), or deleted by a malware infection. Furthermore, AuApplication.dll file corruption could be caused from a power outage when loading Adobe Audition CS6, system crash while loading AuApplication.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.
