John,

You can add an "If X Folder exists Then" Statement to see if a specific folder exists on the target machine.

Then you can use the "Copy File(s)..." script function with the "Do not overwrite existing files" option enabled (if you do not want to overwrite existing files) to copy the files from one folder to another. You can also use the "Copy Folder Tree..." script function to handle it.

You can use the "If X Folder exists Then" Statement to see if a specific folder exists on the target machine. If this is not the case, just display a standard "Select Install Folder" or a Custom Wizard Dialog with folder browse option.

This type of logic always have to be in the Script Editor. From the technical point-of-view, there is no way to handle this from a Visualizer.
