Maybe the first line is a clue, JDK required   >> Eclipse is running in a JRE, but a JDK is required

JDK available here http://www.oracle.com/technetwork/java/javase/downloads/index.html

then try and see what issues you get

Alternative JDK download link https://jdk6.dev.java.net/ 

Once you have done that, you may need to set it by going into windows/preferences/java/installedjre. In fact just look here for other things you may need to do http://tech.karolzielinski.com/m2eclipse-eclipse-is-running-in-a-jre-but-a-jdk-is-required

forget the jre in settings. just try the eclipse.ini
what is your line to jvm.dll?

eg look for something like this. if u find it verify the path
-vm
C:\JavaJDK\Java\jdk1.6.0_01\jre\bin\client\jvm.dll
