There is an issue with ADC Core Utils installations, there will be a .desktop shortcut created into the start menus, i dont know if Gnome and KDE have the same issue as im on MATE but i will try to fix that you can still use Core Utils without .desktop in startmenus.
Expect a fix coming week, i hope i will deploy the fixed tarball before Christmas.
I will create an issue of this on the GitHub page of Core Utils.
