dll_simple.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like dll_simple.dll, are essentially a "guide book" that stores information and instructions for executable (EXE) files - like MpSigStub.exe - to follow. These files were created so that multiple programs (eg. Easy WiFi Radar) could share the same dll_simple.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 dll_simple.dll is attempted to be loaded either when Easy WiFi Radar is starting up, or in some cases already running. Some of the most common dll_simple.dll errors include:
- Access Violation at address - dll_simple.dll.
- dll_simple.dll could not be found.
- Cannot find C:\Program Files (x86)\Makayama Interactive\Easy WiFi Radar\dll_simple.dll.
- Cannot register dll_simple.dll.
- Cannot start Easy WiFi Radar. A required component is missing: dll_simple.dll. Please install Easy WiFi Radar again.
- Failed to load dll_simple.dll.
- The application has failed to start because dll_simple.dll was not found.
- The file dll_simple.dll is missing or corrupt.
- This application failed to start because dll_simple.dll was not found. Re-installing the application may fix this problem.
Your dll_simple.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with Easy WiFi Radar), or deleted by a malware infection. Furthermore, dll_simple.dll file corruption could be caused from a power outage when loading Easy WiFi Radar, system crash while loading dll_simple.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.
