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

I installed jdk 1.8.0_51 64bit on Windows7. After that, no JAVA_HOME was defined, so I had to define it myself as described above, but it did not work unless I added a trailing backslash: D:\Programs\Java\jdk1.8.0_51\.

Without the backslash at the end it did not work.
