mkx.x64.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like mkx.x64.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like mrt.exe - to follow. These files were created so that multiple programs (eg. Media Player Codec Pack) could share the same mkx.x64.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 mkx.x64.dll is attempted to be loaded either when Media Player Codec Pack is starting up, or in some cases already running. Some of the most common mkx.x64.dll errors include:
- Access Violation at address - mkx.x64.dll.
- mkx.x64.dll could not be found.
- Cannot find C:\Windows\System32\mkx.x64.dll.
- Cannot register mkx.x64.dll.
- Cannot start Media Player Codec Pack. A required component is missing: mkx.x64.dll. Please install Media Player Codec Pack again.
- Failed to load mkx.x64.dll.
- The application has failed to start because mkx.x64.dll was not found.
- The file mkx.x64.dll is missing or corrupt.
- This application failed to start because mkx.x64.dll was not found. Re-installing the application may fix this problem.
Your mkx.x64.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Media Player Codec Pack), or deleted by a malware infection. Furthermore, mkx.x64.dll file corruption could be caused from a power outage when loading Media Player Codec Pack, system crash while loading mkx.x64.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.
