System -Settings will not open now.

Since clean install of 32 bit version of Netrunner 16 , on my Dell Inspiron Laptop at first I was able to open System Settings,but when I tried to open Printers,it would not open.I have managed to add my HP 2540 Deskjet,which is a wireless all in one Deskjet by using Localhost:631,now my System Settings will not display at all? I have Netrunner 14 installed on another PC and have not had any malfunction or problems of this kind.Can anyone with better knowledge than me suggest a fix? Michael UK

Not sure, but open a terminal (konsole) and run the command:

systemsettings5

…and see what errors you get - should give a clue.
Cheers
