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