- Download the tracker installer for your platform (Windows, Mac OS X, or Linux) from Tracker's home page at https://physlets.org/tracker/.

2. Launch Tracker
- Windows: choose the Tracker item in the Start Menu.
- OS X: double-click the Applications/Tracker app.
- Linux: search for and double-click the Tracker application.
3. Upgrade Tracker when new versions are released
- When a new version is available, a notification is displayed on the toolbar. To upgrade, click the notification and choose Upgrade Now from the popup menu. For more information about the new version, choose Learn More.
- Most upgrades are instant: the new version or upgrade installer is downloaded and launched immediately. Some upgrades will require that you download a new installer from the Tracker website. Upgrades may include Tracker itself, Java, Xuggle and/or other components.
Congratulations! To start using Tracker, see getting started.
