For this type of application, if you didn't set up a connection when it was started in the first place, a pop-up will appear asking you to do so. Since I didn't find a website or a user guide, I recommend to check the built-in help. In most of the cases you will have all the procedure's steps listed in order to connect a device to PC. Additionally, look through the menu bar for Setup or Settings. In case no solution is viable, reinstall the software and use the connectivity guide to set up the application.
