sl_loadsave_mcos.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like sl_loadsave_mcos.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 sl_loadsave_mcos.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 sl_loadsave_mcos.dll is attempted to be loaded either when MATLAB is starting up, or in some cases already running. Some of the most common sl_loadsave_mcos.dll errors include:
- Access Violation at address - sl_loadsave_mcos.dll.
- sl_loadsave_mcos.dll could not be found.
- Cannot find C:\Program Files\MATLAB\R2019b\bin\win64\sl_loadsave_mcos.dll.
- Cannot register sl_loadsave_mcos.dll.
- Cannot start MATLAB. A required component is missing: sl_loadsave_mcos.dll. Please install MATLAB again.
- Failed to load sl_loadsave_mcos.dll.
- The application has failed to start because sl_loadsave_mcos.dll was not found.
- The file sl_loadsave_mcos.dll is missing or corrupt.
- This application failed to start because sl_loadsave_mcos.dll was not found. Re-installing the application may fix this problem.
Your sl_loadsave_mcos.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, sl_loadsave_mcos.dll file corruption could be caused from a power outage when loading MATLAB, system crash while loading sl_loadsave_mcos.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.
