P3DUI.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like P3DUI.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. Aurora 3D Animation Maker) could share the same P3DUI.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 P3DUI.dll is attempted to be loaded either when Aurora 3D Animation Maker is starting up, or in some cases already running. Some of the most common P3DUI.dll errors include:
- Access Violation at address - P3DUI.dll.
- P3DUI.dll could not be found.
- Cannot find C:\Program Files (x86)\Aurora3D\Animation3D\P3DUI.dll.
- Cannot register P3DUI.dll.
- Cannot start Aurora 3D Animation Maker. A required component is missing: P3DUI.dll. Please install Aurora 3D Animation Maker again.
- Failed to load P3DUI.dll.
- The application has failed to start because P3DUI.dll was not found.
- The file P3DUI.dll is missing or corrupt.
- This application failed to start because P3DUI.dll was not found. Re-installing the application may fix this problem.
Your P3DUI.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Aurora 3D Animation Maker), or deleted by a malware infection. Furthermore, P3DUI.dll file corruption could be caused from a power outage when loading Aurora 3D Animation Maker, system crash while loading P3DUI.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.
