You can replace reference to MessageBox in import table of EXE with some
empty code.

Either inject some code at the target process start and call
SetUnhandledExceptionFilter() with silent handler, or create the target
process under debug API, it allows the 'debugger' to process exceptions
first. There is probably a way to globally disable this exception window,
but can't remember how.
