tools.jar seems to be not in Android Studio classpath on Windows 8

Question

I installed Android Studio but it was giving me error that I need to install JDK but JDK was already installed. Then I realized it is asking to install 64bit version of JDK.

Answer 1

1) Just install JDK from here

2) Change JAVA_HOME variable (e.g. C:\Program Files\Java\jdk1.8.0_112)
