Internet Explorer Users: Check the top of this page for a "Java(TM) Web Start ActiveX Control" message in the information bar. If it appears, click it to finish detecting your Java version.

We were unable to detect a recent version of Java Runtime Environment (JRE) on your system. With the latest JRE, you can automatically download, install, and run Sun Download Manager (SDM) directly from this page. We highly recommend SDM to easily manage your downloads (pause, resume, restart, verify, and more). Visit java.com for the latest JRE.
