>where could i find the config.fpw? As what i observed when i am using the visual studio to create a setup application, its output exe will create the two foxuser.dbf and foxuser.fpt in the desktop where my exe shortcut is located.

It may be in the same directory as your VFP project or may not exists at all because it's not required to run your application. You can always create it with any text editor, MODIFY FILE, for example. After that you can include config.fpw in your project or copy it to the same directory as EXE during install.
