After install or upgrade of the Data Center Security (DCS) 6.9.0 or 6.9.1 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.
DCS 6.9.0 Java Management Console
DCS 6.9.1 Java Management Console
Manually delete the \ext folder and logon to the Java Management Console will be successful.
Location of \ext folder:

This permission requirement is noted in the DCS 6.9.0/6.9.1 Planning and Deployment Guide.
