title: Problems setting the JAVA_HOME variable
body: <p>So I just downloaded Android Studio, and am trying to set the JAVA_HOME variable so I can run it. I'm using windows 8 and have followed all the instructions I've been able to find to no avail... went to advanced system settings > environment variables and then set the JAVA_HOME variable with the value containing my path to jre7. I've double checked the path a million times, I don't see anything wrong with it(C:\Program Files (x86)\Java\jre7). I know the variable name is right, and I know that windows is excepting the variable, I've even restarted twice. What am I doing wrong here? The only thing I can think of that may be wrong is the fact that I'm pointing to a jre instead of a jdk, but I've always thought that both worked... anyway, the exact error message I get when I try to open Android Studio says:</p>
  
  <blockquote>
    <p>No JVM installation found. Please install a 64-bit JDK. If you already
    have a JDK installed, define a JAVA_HOME variable in Computer > System
    Properties > System Settings > Environment Variables.</p>
  </blockquote>
  
  <p>If a jre doesn't work in place of a jdk, then how do I go about getting one? I know nothing about Java I just want to get into this IDE and play around with Android.</p>
