Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

In my first computer I clicked on software center,scrolled to LibreOffice Base and made 1 click to open Base(as I recall). On my 2nd computer I clicked on software center, scrolled to LibreOffice Base and a click brought up 'Available from the "main" source'. What did I do wrong and how do I open applications in the Software center?(no terminal scripts). The same CD loaded both systems. This edit is to say I just remembered my 1st computer was on line and the 2nd was not. When I got the 2nd computer on line the application loaded OK. I do not know the procedure for responding to the answeres so let me say they are appreciated.

Ubuntu Software Center is not used for running applications. It is for purchasing, installing, and removing applications. If you want to run an application that is installed, simply open the dash by clicking on the Ubuntu logo on the top of the left bar (launcher), and you can search for the application, and run it. Or you can switch to the Applications view there, and browse your installed applications, as well as possibly some recommended apps.

LibreOffice Database is not installed by default on 12.04. You must install it before you can launch it. The software center is for installing/uninstalling applications, not launching them. To launch an application you can use the "Dash Home" button on the unity sidebar.
