'Failed Binding' error when selecting 'Customize Rules'

I'm using Fiddler v4.6.20173.38786 (Built: Friday, September 15, 2017). When I click on the Customize Rules menu entry there is a message box that says "Unable to load Fiddler for code-completion support". After I click OK to that the Fiddler script editor will open normally.

    Everything described above is still an issue in build Dec-14-17 v5.0.20173.50948 installer which is the latest version.
