I've been trying to achieve that for the last 2hrs. Can anyone help me out please? I'm trying to pass the installation directory to the custom action.

              Have you tried accessing Context.Parameters["TARGETDIR"] from the custom action?

              not yet, but this does sound good indeed. I'll give it a go.
