Today I tried to install visual editor and every link I found lead or to 404 page or to http://www.eclipse.org/archived/ which tells that it was archived in the previous month. Are there any update site left I can use to install visual editor? I am just not happy to download 400+ megabytes to install visual editor offline.
I believe Visual Editor is deprecated.
Instead, you should probably install WindowBuilder which is available either as a plug-in or as part of the official Eclipse 3.7 Indigo release for Java developers.
My impression is that WindowBuilder is a very good GUI-building tool and will be the main GUI editor for Eclipse in the future.
