I have a JAVA_HOME variable set to:
C:\Program Files (x86)\Java\jdk1.7.0_45\ And the path to the jdk is: C:\Program Files (x86)\Java\jdk1.7.0_45
However when I try to start android studio I get the error:
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.

The Android Studio make use of JAVA_HOME environment variable to find the JVM installation. If you have not set the JAVA_HOME then you must do so by going into My Computer -> System Properties -> System Settings ->Environment Variables. Make sure your JAVA_HOME points to 64-bit JDK installation e.g. JDK 1.8.
Download Liberica JDK and on installation it will automatically set JAVA_HOME environment variable. Now you just go to Android Studio -> Project Structure -> SDK -> Point all jdk path to liberica jdk installation directory and apply. You are done. Just restart android studio and gradle command will work.
To set JAVA_HOME, do the following: Right click My Computer and select Properties. On the Advanced tab, select Environment Variables, and then edit JAVA_HOME to point to where the JDK software is located, for example, C:\Program Files\Java\jdk1.
If any program that requires a Java runtime fails to find the JAVA_HOME environment variable upon startup, or if the JAVA_HOME environment variable is misconfigured, it will result in some of the following error messages to be displayed: A Java installation exists but JAVA_HOME has been set incorrectly.
It says that it should be a 64-bit JDK. I have a feeling that you installed (at a previous time) a 32-bit version of Java. The path for all 32-bit applications in Windows 7 and Vista is:
C:\Program Files (x86)\ You were setting the JAVA_HOME variable to the 32-bit version of Java. Set your JAVA_HOME variable to the following:
C:\Program Files\Java\jdk1.7.0_45 If that does not work, check that the JDK version is 1.7.0_45. If not, change the JAVA_HOME variable to (with JAVAVERSION as the Java version number:
C:\Program Files\Java\jdkJAVAVERSION Here is the tutorial :- http://javatechig.com/android/installing-android-studio and http://codearetoy.wordpress.com/2010/12/23/jdk-not-found-on-installing-android-sdk/
Adding a system variable JDK_HOME with value c:\Program Files\Java\jdk1.7.0_21\ worked for me. The latest Java release can be downloaded here. Additionally, make sure the variable JAVA_HOME is also set with the above location.
Please note that the above location is my java location. Please post your location in the path
