Help appreciated!

Yeah, you should have a JDK installed (preferably 64-bit as your OS is 64-bit) and set the JAVA_HOME path variable to that location. — midhunhk, Nov 28 '13 at 07:09

As people suggested in comments, you should install JDK. To maintain the difference, refer to: What is the difference between JDK and JRE?.

There are a lot of guides on the internet but the easiest way to install JDK is to visit Oracle Downloads page and install the required one.

After installing read official guide how to set up environment.
Also, this question is answered in SO: How to set JAVA_HOME on Windows 7?

After this, Intellij IDEA (Android Studio) will fetch JDK automatically. If not, go to Project Structure and set up JDK path manually:
