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

You need 1.7 JDK installed on your system. Add a system variable with:

• name: ANDROID_STUDIO_JDK

• path: your JDK path (for example, C:\Program Files\Java\jdk1.7.0_21)

  • See more at FIX: Android Studio - Installation Issues on Windows 7 | ERROR: cannot start Android Studio. No JDK found.

Answer 2

On Windows 10, restarting the installer and running as admin worked for me.

Answer 3

Install the latest JDK in your system from JDK 7 and JRE 7 Installation Guide.

JAVA_HOME -> C:\Program Files\Java\jdk1.7.0_4
path -> C:\Program Files\Java\jdk1.7.0_4\bin

Answer 4

If you have a 64 bit windows OS, pointing the JAVA_HOME system variable to

C:\Program Files (x86)\Java\jdk1.7.0_21

Will work when

C:\Program Files\Java\jdk1.7.0_21

fails to work.

Answer 5

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.

Answer 6

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.
