Q36: How do I know if my Java ES uninstallation succeeded?

Answer: One way to determine if the uninstallation succeeded is to compare the packages listed in the installation log with the packages listed in the uninstallation log. You can also check the product registry to verify that Java ES components have been removed. See Q40: What is the product registry and why should I care about it?

In some cases, the uninstaller does not remove all of the packages or directories. You might not discover this situation until you try to do a new Java ES installation. If this occurs, check the appropriate troubleshooting write ups for guidance on removing files or components that are left behind.
