Dear

Could be some problem about JDK configuration, open a command windows and execute : java -version

Take a look to the result of SET command ? It prints all the system variables.

And check inside <Knowage installation dir>/logs if some logs are written.

Best Regards

Angelo

Hi,

you must set the JAVA_HOME environment variable after the installation of the JDK 1.7.

Once you have the JDK installation path:

  • Right-click the My Computer icon on your desktop and select Properties.
  • Click the Advanced tab.
  • Click the Environment Variables button.
  • Under System Variables, click New.
  • Enter the variable name as JAVA_HOME.
  • Enter the variable value (one of the paths mentioned above) as the installation path for the Java Development Kit (ex: C:\Program Files\Java\jdk1.7.0_71)
  • Click OK.
  • Click Apply Changes.

You might need to restart windows.
