SDK Manager.exe doesn't work

Question

When I clicked SDK Manager on Program Files or run it in cmd, nothing happened. I did:

1. Installed latest JDK
2. Installed latest Android SDK<

Answer 1

What I did was:

set a new environment variable in the top user section.

VARIABLE NAME: JAVA_HOME VARIABLE VALUE: set it to the installation directory of your most recent JDK.

For me it was, C:\Program Files\Java\jdk1.7.0_13 . Run SDK Manager as administrator at least once. I use windows 7. This method worked for me after a lot of research.

What I dont understand is when using 'where java' in the command prompt it still references C:\Windows\System32\java.exe. My SDK Manager now opens when I need it so I solved my problem.
