Android studio doesn't start

Question

I just download Android Studio for Windows 7, the wizard went ok up to the end but now when I click on the shortcut or on the .exe to start the program nothing happens, no error, no new window, it's seems like it is doing nothing. Do you have any suggestion?

Answer 1

It's a bug of Android Studio 0.1v

You should add JAVA_HOME to the system environment variables.

• Open Start menu > computer > System Properties > Advanced System Properties
• In the Advanced tab > Environment Variables, add new system variable JAVA_HOME that points to your JDK folder, for example C:\Program Files\Java\jdk1.7.0_21

Answer 2

1. Install latest Java Development Kit.
2. Set path in system variables for Java (ie *C:\Program Files\Java\jdk1.7.0_21\bin*)
3. Set JDK_HOME system variable (ie *C:\Program Files\Java\jdk1.7.0_21*)
4. If not working, set JAVA_HOME in system variable too (ie *C:\Program Files\Java\jdk1.7.0_21*)
5. If not working, check if you don't have spaces at the ends of the lines in system variables (PATH, JDK_HOME, JAVA_HOME)

You don't have to restart computer after changing system variables, just reload command prompt (if you are using it).

If it still not working, you probably have java.exe in C:/Windows/System32/. Rename it, restart command prompt and type java -version to check if you are using correct version of JDK.
