Jochen's suggestion of using the debugging interface is probably the best
approach, but another would be to inject code into the target processes which
executes SetUnhandledExceptionFilter to install your own exception handler.
It won't be trivial to do this without interfering with exception handling
within the program but it won't be trivial to implement your own debugger
either.
