I'm working with the Windows installer and need to programmatically
get a hold of the Application Folder value (in a custom step). I.e.
Application Folder value gets set in the Folder field of the
Installation Folder User Interface Dialog Box, and I have a custom
step that needs to retrieve this value.
MSDN mentions TARGETDIR property value and so on but really lacks
specifics on how to get a hold of this dynamically changing value.
I need the value as my install target dir contains some readme input
files that i'm displaying in custom GUIs during installation.
thanks, dave
