I followed this video:
and installed the juno plug in.

there were no errors during the installation. Nevertheless, when I try to create a new application window I get this error:
Plug-in "org.eclipse.wb.core.ui" was unable to instantiate class "org.eclipse.wb.internal.core.editor.multi.DesignerEditor".

I tried uninstall and reinstalling it twice.

Does anyone knows how to install it correctly and make it work?

Had same issue, it was due to installing the software for the wrong version of eclipse.

In video he uses Juno I was using oxygen hence it wouldn't work.
Ensure you are using the right link to install software from.
