I installed jdk 1.7 from: It's jdk 7u6

I added 1.7 SDK to IntelliJ:

You might need to add the jre/lib/rt.jar file to your compiler classpath as well as the ones you have.

My Windows SDK has all these libraries:

  • jdk\jre\lib\charsets.jar
  • jdk\jre\lib\deploy.jar
  • jdk\jre\lib\javaws.jar
  • jdk\jre\lib\jce.jar
  • jdk\jre\lib\jfr.jar
  • jdk\jre\lib\jsse.jar
  • jdk\jre\lib\management-agent.jar
  • jdk\jre\lib\plugin.jar
  • jdk\jre\lib\resources.jar
  • jdk\jre\lib\rt.jar
  • jdk\jre\lib\ext\dnsns.jar
  • jdk\jre\lib\ext\localedata.jar
  • jdk\jre\lib\ext\sunec.jar
  • jdk\jre\lib\ext\sunjce_provider.jar
  • jdk\jre\lib\ext\sunmscapi.jar
  • jdk\jre\lib\ext\zipfs.jar

And it doesn't have any of the jdk\lib\*.jar files you have listed.
