Hi,
I'm trying to build an installer, that during the install of a newer version checks to see if a configuration file exists from the previous version and presents a dialog to keep the previous configuration or install "normally" if you will.
My thoughts are to have a custom action that hangs off the next button on the dialog before the verify ready dialog and present an optional dialog if the config is found with a checkbox to keep the previous config, but I'm not entirely sure how to do this.
Any help is much appreciated.
Kind regards,
Lee
