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