Adding XML config files along with package using Installshield 2016
> Installation Designer Tab> Left panel -> System Configuration
* Create a component for your existing development XML file and include the XML file in it. Set all of the attributes for the file properly (key file, target location, etc.)
* Switch to XML view and use the import wizard. Only import the keys you want to change
* Once the wizard is done, select the file itself and set the XML File Destination to match the XML file you're modifying.
* Change the search patterns for the keys you want to modify. For some reason, the IDE shows this as the Element Name - this is actually the XPath query to find the element.
* Delete anything in the attributes section that you aren't trying to change
* Set the Value of your attribute as necessary and set the operation to Append Value.
* Switch to advanced view and make sure that only "Update first matching element only" is checked (unless you want to replace multiple, identical elements )
