title: Intellij IDEA can not find tools.jar
body: <p>I install Intellij IDEA 15.0.2 on Windows 8.1, run it, it asked for the path to jdk, i choose directory with JDK, and then IDEA worked correctly. But after reload of PC, I get this error message from IDEA - <code>'tools.jar' seems to be not in IDEA classpath.</code>.So, I check JAVA_HOME from command line, check for tools.jar in <code>JDK_directory/lib</code>, everything is on their places, how to run IDEA?</p>
