bmctr.dll is considered a type of Dynamic Link Library (DLL) file. Dynamic Link Library files, like bmctr.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. My WiFi Router) could share the same bmctr.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 bmctr.dll is attempted to be loaded either when My WiFi Router is starting up, or in some cases already running. Some of the most common bmctr.dll errors include:
- Access Violation at address - bmctr.dll.
- bmctr.dll could not be found.
- Cannot find C:\Program Files (x86)\Wi-Fi\bmctr.dll.
- Cannot register bmctr.dll.
- Cannot start My WiFi Router. A required component is missing: bmctr.dll. Please install My WiFi Router again.
- Failed to load bmctr.dll.
- The application has failed to start because bmctr.dll was not found.
- The file bmctr.dll is missing or corrupt.
- This application failed to start because bmctr.dll was not found. Re-installing the application may fix this problem.
Your bmctr.dll file could be missing due to accidental deletion, uninstalled as a shared file of another program (shared with My WiFi Router), or deleted by a malware infection. Furthermore, bmctr.dll file corruption could be caused from a power outage when loading My WiFi Router, system crash while loading bmctr.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.
