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