title: "There are no JREs installed in the workspace that are strictly compatible with this environment."
body: <p>I just downloaded the "Eclipse IDE for Java Developers" and I opened it up, started it up and got the error "Build path specifies execution environment CDC-1.1/Foundation-1.1. There are no JREs installed in the workspace that are strictly compatible with this environment.". I have no idea what this mean, as I'm still trying to wrap my had around all this java stuff. I look at my installations and I see this:</p>
  
  <ul>
  <li>Java 7 Update 60</li>
  <li>Java 8 Update 5 (64-bit)</li>
  <li>Java SE Development Kit 8 Update 5 (64-bit)</li>
  </ul>
  
  <p>Please help, I have no idea what I'm doing or what to do.</p>
