Pack 200 Support

Platform's JVM version does not support Pack 200.


The Pack 200 check box is selected under the Advanced options on the Select files panel. Pack 200 support requires JVM 1.6 or later.

You can (1) change the required version on the JVM panel and make sure that you're running JExpress itself with Java 1.6 or later; or (2) disable Pack 200 in the Select files panel's Advanced options.
