PackageMaker Custom UI Dialog

I'm using PackageMaker to build an installer package for my OS X application. I need to customize the dialog that the user sees when installation fails (return non-zero value from post install script). The Edit Interface dialog in PackageMaker does not list the error dialog. Is there a way to manually modify the PackageMaker project to customize this dialog?

From stackoverflow

• I don't think this is possible, at least from the PackageMaker UI.

• Hi John McCann. PackageMaker donot give functionality to change the UI. You can only change the message that U want to show to the client. Almost non of the third party installer give the functionality to change the UI.

  Thanks Sunil Kumar Sahoo

  Deepak : I think you have to post question in serverfault. Because it is not programming related

  Girish Kolari : is it possible to change the error string without changing the UI?
