This functionality is supported only if you are using the Classic Agent.
You may edit the configuration file for just your application or you may edit the configuration file for your entire machine. If you do not have a configuration file, you may create one; see the sample file if you are interested in creating one.
If you want to change the application configuration, you need to do so on the machine where the application .exe is, in the same directory as that .exe. This approach establishes a "default" configuration that is associated with the application.
If you want to change the machine configuration, you need to do so on the machine where the application will run (which is the same location as the Silk Test Agent). This approach establishes a configuration that will override any application configuration that may exist.
In either case, you can use the direct file editing or the Control Panel to edit the configuration file.
