Com.google.appengine.tools.enhancer.Enhance not found in Google App Engine project

I installed the Google Plugin for Eclipse and created a new Google App Engine project as described at https://developers.google.com/appengine/docs/java/tools/eclipse . When I create a project, I get an error Error: could not find or load the main class com.google.appengine.tools.enhancer.Enhance

I was looking for similar questions in stackoverflow, and the only suggestions were to use JDK 7 and remove any existing JDK 6, even if it was not listed in Eclipse Installed Jres. I have done both, and I am still facing the same error. This is on a computer with Windows 7 x64, and Eclipse and JDK are 32-bit. I also tried on another computer, which is a Windows Server 2008 x64 machine, and again 32-bit Eclipse and JDK. I also encounter the same error.

Please help before I shoot myself.

If you are not using JDO / JPA, clear the check box for this option on the App Engine tab for your project.
