In the mac lab I teach in, At Ease is used to keep kids out of the sensitive system folders, etc. On one of the computers, however, I cannot utilize the At Ease set-up utility to add, remove etc. application shortcuts to the At Ease menus. The error message states that the version of At Ease installed on this computer is not compatible with this version of At ease administration. It appears that At ease has been installed several times on this hard drive (these computers were not set-up by me, and the hard drives are rather messy); none of the installed At Ease programs has a set-up that will work.
How should I rectify this problem. Should I just trash all of the At ease files and preferences, and just install fresh? My only fear is that when the computer starts up, it defaults to the At Ease menu; would uninstalling all the At Ease files affect the start-up?
