It took me some time to find such a tool. I recall that is named SQLiteSheet. But once I downloaded the software, it shows me SQLite Database browser. And the software points me to a web site, sqlitebrowser.sourceforge.net. But at that site I could not the same software I have downloaded, a graphical tool. Stupid I could not find my link again.
Anyone knows similar tool to open the .db3 file under \Application Data\LANDesk\ManagementSuite\Database directory?
