Are you sure you installed the game to your computer, or are you playing it from your browser?
The game can be played both ways. A full install of the launcher and the game should give you an icon on your desktop, and takes quite a while to complete. Launching the game from a web browser only installs a little bit, and you would erlaunch from the web browser every time.
