I installed Itellij IDEA 15.0.2 on Windows 8.1, when I first started, she asked for the path to the JDK, I did it, after which it worked successfully. However, after restarting the computer, at startup it gave the error 'tools.jar' seems to be not in IDEA classpath. . I checked the JAVA_HOME command line, checked the availability of tools.jar in JDK_directory/lib , which is specified in the variable, everything is in place, what could be the problem?
When you start from the idea.exe shortcut, an error crashes, if you run idea64.exe - everything works.
