Download the distribution zip but don't unzip it. Create a new Eclipse project named OP2010. When you create the project use the Next> button to get to where you can add a Libarary and add the JUnit.jar (JUnit 4) as a library. With only this new project open, right click on the project icon and select Import. From the wizard, select Archive. In the next pane, browse/navigate to the zip file you downloaded and select it. Then hit SelectAll button. The text field at the bottom should show the name of your project as the directory to import into. Click Finish. You are completely installed. Do a full build of the project (project menu). Do a Run with SystemTest as the main. You should get a green bar.
