If all else fails, use the WinDbg debugger to inspect address 0043C7AC – you will likely find a null pointer dereference or a function call to an unloaded DLL. For most users, however, Fixes 1 through 5 above will restore normal operation without ever touching a debugger. For most users, however, Fixes 1 through 5
A helpdesk ticket at a mid-size accounting firm reported the exact error: "Access violation at address 0043C7AC in module statusmonitorexe upd" appearing every 20 minutes on Windows 10 workstations. Follow this systematic diagnostic process

Here are the solutions ranked by user skill level, from easiest to most technical.
