Software manager not opening from Menu ?

Well I've had this problem for ages after I messed about with menu editing in order to create a new folder showing my Emulators.
Lots of searches later I finally found the issue. I'd had an inkling it was because the application needed to be called from root. I initially put "sudo makeinstall" as the call in the command text box after opening properties in edit menu (right click on the menu in the left hand corner).
This did not work. I finally found I was correct but the command was "gksu mintInstall".
Fixed !
