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