mcli18nutil.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mcli18nutil.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like klist.exe - to follow. These files were created so that multiple programs (eg. MATLAB) could share the same mcli18nutil.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 mcli18nutil.dll is attempted to be loaded either when MATLAB is starting up, or in some cases already running. Some of the most common mcli18nutil.dll errors include:
- Access Violation at address - mcli18nutil.dll.
- mcli18nutil.dll could not be found.
- Cannot find C:\Program Files\MATLAB\R2019b\bin\win64\mcli18nutil.dll.
- Cannot register mcli18nutil.dll.
- Cannot start MATLAB. A required component is missing: mcli18nutil.dll. Please install MATLAB again.
- Failed to load mcli18nutil.dll.
- The application has failed to start because mcli18nutil.dll was not found.
- The file mcli18nutil.dll is missing or corrupt.
- This application failed to start because mcli18nutil.dll was not found. Re-installing the application may fix this problem.
Your mcli18nutil.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with MATLAB), or deleted by a malware infection. Furthermore, mcli18nutil.dll file corruption could be caused from a power outage when loading MATLAB, system crash while loading mcli18nutil.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.
