Hi Afzaal,
when you launch the knowage_startup.bat file, does the command prompt start to run or stay blinking?
In the latter case, please wait some minutes before you close the command prompt because sometimes it take a bit to run.
Furthermore, have you checked that all information contained in the RUNNING.txt file (available in the Knowage folder), such as the JAVA_HOME variable and the Java application itself, are correctly configured?
Regards,
Nunzia
