Error launching Android Studio

Question

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.

Answer 1

This is because you did not set up the system environment variable of jdk for Android Studio.

1. System Properties -> Environment Variables... -> System variables -> New...
2. Variable name:ANDROID_STUDIO_JDK -> Variable value:X:\Program Files\Java\jdk1.8.0_20 (where you installed the jdk) -> OK.
3. That's all, try to run your android-studio\bin studio.exe again.
