Prerequisites

Java 6 (Java JRE 1.6) or later must be installed on the machine using Java CodeWatch for debugging.
Make sure you are logged with your personal account and not with the Windows SYSTEM account when starting the ES region from the ESMAC Web user interface or the Visual Studio interface, otherwise the debugger will not start up. This is due to the SYSTEM account not having an active Windows desktop in which to display the debugger interface to the user.
