I am afraid that you will need to install the suite again. You can do this using the Support CD of your laptop. Alternatively, if you believe that the application and driver are installed, go to Control Panel > Hardware and Sound. If the Bluetooth is installed, you should see its icon. A double-click will launch its configuration window from where you can make it to be shown in the notification area. If the icon is missing, it's necessary to install its corresponding drivers.
