   A Java Setup - Progress pop-up window will appear, with the following message at the top of the window: Status: Installing Java

   

   A green progress bar will appear, showing the progress as it installs Java, and will finally disappear (on my machine this took about 30 seconds).

   If a Java Setup - Uninstall out-of-date versions pop-up window appears

   

   Click the Uninstall > button; if you are concerned that other software you have may need an older verison of Java, click the Not Now button. You may want to click the More information link, which recommends uninstalling older versions of Java.

   I clicked Uninstall > and the following pop-up window was displayed while it unistalled the second version.

   

   It unsintalled two out-of-date versions, and the following Java Setup - Complete pop-up window appeared.

4. Click Close

   If you know how to bring up system prompt/cmd window, you can test the Java installation by typing java -version to the prompt and pressing the Enter key. It should show the following.

   

   After seeing this message (look for java version "1.8.0_221" on the line after the command) or an error message, type exit in the cmd.exe window and press the Enter key.

You can now follow the instructions to download and install Python and then the Eclipse IDE.
