Could try with Ruby 2.0 or 2.1? ## Thanks, kou ---

I was successful in using ruby2.0 on windows 7 and also Windows 8, with the fresh install of glade3-3.6.7-with-GTK+.exe and visualruby. Many thanks for the timely response and a working solution. PS if you upgrade from ruby 1.9 to ruby 2.0 be sure the the file associations of .rb & .rbw have been updated. John ---

We may wish to update the Visual Ruby web site as it currently indicates the installation of ruby1.9.3 is required. New to this forum and Visual Ruby, adny advice on getting the page changed? Shall I log a defect against the page?
