p3shared.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like p3shared.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. Euro Truck Simulator) could share the same p3shared.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 p3shared.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 p3shared.dll errors include:
- Access Violation at address - p3shared.dll.
- p3shared.dll could not be found.
- Cannot find C:\Program Files (x86)\Euro Truck Simulator\p3shared.dll.
- Cannot register p3shared.dll.
- Cannot start Euro Truck Simulator. A required component is missing: p3shared.dll. Please install Euro Truck Simulator again.
- Failed to load p3shared.dll.
- The application has failed to start because p3shared.dll was not found.
- The file p3shared.dll is missing or corrupt.
- This application failed to start because p3shared.dll was not found. Re-installing the application may fix this problem.
Your p3shared.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, p3shared.dll file corruption could be caused from a power outage when loading Euro Truck Simulator, system crash while loading p3shared.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.
