Eclipse not opening, downloaded Eclipse ADT bundle

Question

I have a Windows 7, 64-bit operating system. I downloaded the Eclipse ADT bundle from http://developer.android.com/sdk/index.html . I verified that I downloaded the 64 bit version and have downloaded the 64-bit version of the Java Development Kit. I unzipped the file and tried to run eclipse.exe but nothing happens, no error but eclipse doesnt open. I deleted and re-downlaoded the Eclipse ADT bundle hoping that it would fix the problem but no luck. Any one know any solutions?

Answer 1

Most probably, eclipse can't find the java binary in your computer, and it fails to launch.

You can check if java binary is correctly set just typing this in the command line:

java -version

If it doesn't show you any version number, that's it.

If you haven't restarted Windows since you installed the JDK, try restarting Windows so you are sure that Windows is aware of the new binary.

If that doesn't work, you can uninstall the JDK, restart, and install the JDK again.

Note: most of the application won't care about it, but sometimes JDK7 can give you problems. I'd recommend you installing JDK6. Anyway, that's entirely your choice.
