WSMediator.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like WSMediator.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like 7z.exe - to follow. These files were created so that multiple programs (eg. QuarkXPress) could share the same WSMediator.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 WSMediator.dll is attempted to be loaded either when QuarkXPress is starting up, or in some cases already running. Some of the most common WSMediator.dll errors include:
- Access Violation at address - WSMediator.dll.
- WSMediator.dll could not be found.
- Cannot find C:\Program Files\Quark\QuarkXPress 2019\XTensions\WelcomeScreen\WSMediator.dll.
- Cannot register WSMediator.dll.
- Cannot start QuarkXPress. A required component is missing: WSMediator.dll. Please install QuarkXPress again.
- Failed to load WSMediator.dll.
- The application has failed to start because WSMediator.dll was not found.
- The file WSMediator.dll is missing or corrupt.
- This application failed to start because WSMediator.dll was not found. Re-installing the application may fix this problem.
Your WSMediator.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with QuarkXPress), or deleted by a malware infection. Furthermore, WSMediator.dll file corruption could be caused from a power outage when loading QuarkXPress, system crash while loading WSMediator.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.
