i have a POS system computer (Advanced APT AP15) which already has an ubuntu 12.04 LTS installed and i want to install an 14.04 Ubuntu, i'm using an live USB, when the installer starts the touch screen does not works,so i can't select "Try Ubuntu" or "install Ubuntu"

My question it's, i can install ubuntu using a USB mouse and then configure the touch screen later? and how i can do that?

If it already has 12.04 then you can just upgrade but typing sudo do-release-upgrade in a terminal then inputting your password. Also if you can do the install with a mouse then go back to a regular boot, run a dpkg-repack (I'll give you a link in a bit) and save that to a USB then you can reinstall all the drivers later... Just don't blame anyone if you get compatibility issues if you do that.
