    1. The JRE installation starts:


    The installer unpacks the files needed to continue. A dialog box tracks this process, which takes less than a minute. After briefly displaying a logo splash screen, the installer presents the license agreement.

    After reading the agreement, click the Yes button to accept its terms and continue with the installation.

    The installer then displays a Setup Type screen that allows you to choose either a typical or custom setup. We recommend that you choose the Typical option (the default selection) unless you are an advanced user who wants more precise control over the components that will be installed.

    After ensuring that the Typical setup is selected, click the Next button to continue with the installation.

    Now that you have given the installer all of the information it needs to proceed, progress boxes track the installation process.
