Trace Activation
The traces of the product are aids in detecting failures, since they record all the steps of the product execution.
To enable activity logs (Traces) access the Windows registry and follow the path HKEY_LOCAL_MACHINE\SOFTWARE\NDDigital\n-Billing\n-MF\Lexmark. Inside this folder, create a String Value called Debug and set it's Value as True. After creating these keys, restart the service NDDigital n-MF Lexmark to start generating the logs.
The traces are created in the installation directory, in the sub directory Trace.
