Android Studio installation on Windows 7 fails, no JDK found

Question

I downloaded Android Studio and attempted to launch the program.

This is running on Windows 7 64-bit with Java 1.7. During the installation my Java 1.7 is detected,

Answer 1

1. Add JAVA_HOME and JDK_HOME system environment variables.
2. Right-click android studio (the 64 version if that's your OS and JDK) and go to compatibility tab and set "Run as administrator" to true.
3. Run android studio and high-five me virtually when it works.
4. If that fails, try "where java" in cmd.exe. If it lists c:\system32\java.exe first, then rename the file and try again.
