Description
Dear today
after long time that i used the old version of windowbuilder (nightly build) on the eclipse market place
i decide to upgrade to the latest version
then i proceed with the unistall of the old version and install the new one by the path
https://download.eclipse.org/windowbuilder/latest/
the installation completed succesfully but after the restart of eclipse
the "palette new" doesn't have more any reference to the windows builder elements
moreover now when i try to go to open in the menu hepl > install new software
I receive this error that looks like related to windows builder
moreover if i try to access to the eclipse marketplate by the help menu, eclipse stay stuck forever
