Access Violation At Address 0043c7ac In Module Statusmonitorexe Upd May 2026

The operating system terminated the process because the application attempted to read from or write to a memory address (0043c7ac) that was either invalid, protected, or currently paged out. The suffix upd likely indicates the crash occurred during or immediately following an update routine.

    How to Fix "Access Violation at Address 0043C7AC" in StatusMonitor.exe

    If you are seeing a popup error that reads "Access violation at address 0043C7AC in module StatusMonitor.exe," you are likely using a Brother printer. This specific error is a common glitch within the Brother Status Monitor utility, usually triggered when the software tries to access a protected memory address that it doesn't have permission to use.

    Before diving into deeper fixes, try clearing the current "stuck" instance of the program. Press Ctrl + Shift + Esc to open the Task Manager. Go to the Details or Processes tab. Locate StatusMonitor.exe. Right-click it and select End Task.

    Restart your computer. In many cases, a fresh reboot reallocates the memory correctly. Step 2: Run in Compatibility Mode
