file_key_management.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like file_key_management.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like ApacheMonitor.exe - to follow. These files were created so that multiple programs (eg. WampServer) could share the same file_key_management.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 file_key_management.dll is attempted to be loaded either when WampServer is starting up, or in some cases already running. Some of the most common file_key_management.dll errors include:
- Access Violation at address - file_key_management.dll.
- file_key_management.dll could not be found.
- Cannot find C:\wamp64\bin\mariadb\mariadb10.3.14\lib\plugin\file_key_management.dll.
- Cannot register file_key_management.dll.
- Cannot start WampServer. A required component is missing: file_key_management.dll. Please install WampServer again.
- Failed to load file_key_management.dll.
- The application has failed to start because file_key_management.dll was not found.
- The file file_key_management.dll is missing or corrupt.
- This application failed to start because file_key_management.dll was not found. Re-installing the application may fix this problem.
Your file_key_management.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with WampServer), or deleted by a malware infection. Furthermore, file_key_management.dll file corruption could be caused from a power outage when loading WampServer, system crash while loading file_key_management.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.
