The application will be added to the Downloads section on the toolbar. Click on the app once it's in the Downloads section, hit Install, and it will automatically install on your computer. Once it's installed, the Zoom app will show up as a blue video icon on the toolbar. Click on it, and you will be prompted to join a meeting or sign in.
