In your case what is the error message?
By default, JRE comes with the strong cryptography version of JCE, but LiveUpdate requires the unlimited version. Make sure your system is now using the correct JRE.
For example:
# java -version
java version 1.8.0_91
Java(TM) SE Runtime Environment (build 1.8.0_91-b15)
Java HotSpot(TM) Client VM (build 25.91-b01, mixed mode, sharing)
Did you Download and replace right version of Unlimited Strength Cryptography (JCE) files? If not download it from:
http://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html (based on Java version)
Extract contents and copy to /lib/security.
# unzip jce_policy-8.zip
# cd UnlimitedJCEPolicyJDK8
# cp local_policy.jar US_export_policy.jar /usr/java/jre1.8.0_91/lib/security
Finally try this:
# /usr/java/jre1.6.0_23/bin/java -cp /opt/Symantec/LiveUpdate/jlu.jar com.symantec.liveupdate.config.editor.ConfEditor
It should work. If this is not working, please provide the error message.
Cheers !!!
