oauth.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like oauth.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like FileCoAuth.exe - to follow. These files were created so that multiple programs (eg. MAGIX Music Maker) could share the same oauth.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 oauth.dll is attempted to be loaded either when MAGIX Music Maker is starting up, or in some cases already running. Some of the most common oauth.dll errors include:
- Access Violation at address - oauth.dll.
- oauth.dll could not be found.
- Cannot find C:\Program Files (x86)\MAGIX\Music Maker\28\Online\oauth.dll.
- Cannot register oauth.dll.
- Cannot start MAGIX Music Maker. A required component is missing: oauth.dll. Please install MAGIX Music Maker again.
- Failed to load oauth.dll.
- The application has failed to start because oauth.dll was not found.
- The file oauth.dll is missing or corrupt.
- This application failed to start because oauth.dll was not found. Re-installing the application may fix this problem.
Your oauth.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with MAGIX Music Maker), or deleted by a malware infection. Furthermore, oauth.dll file corruption could be caused from a power outage when loading MAGIX Music Maker, system crash while loading oauth.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.
