After install or upgrade of the Data Center Security 6.9.0 Java management console, users are unable to log on to console, and an error is produced.
When you install or upgrade the Java Management Console, you must have delete permissions on the installation folder. Windows User Account Control and SmartScreen will not allow this permission, thus should be disabled during install or upgrade.
Without this permission, the Java Management Console fails to load.
