5. Click the install icon next to the uninstaller that matches the update you want 

to remove.
The Install Update page appears. 

6. Select the Defense Center and click Install, then confirm that you want to 

uninstall the update and reboot the device.
The uninstallation process begins. You can monitor the uninstallation 

progress in the task queue (System > Monitoring > Task Status).

Do not use the web interface to perform any other tasks until 

the uninstallation has completed and the Defense Center reboots. Before the 

uninstallation completes, the web interface may become unavailable and the 

Defense Center may log you out. This is expected behavior; log in again to 

view the task queue. If the uninstallation is still running, do not use the web 

interface until the uninstallation has completed. If you encounter issues with 

the uninstallation (for example, if the task queue indicates that the update has 

failed or if a manual refresh of the task queue shows no progress for several 

minutes), do not restart the uninstallation. Instead, contact Support.

7. After the uninstallation finishes, clear your browser cache and force a reload 

of the browser. Otherwise, the user interface may exhibit unexpected 

behavior.

8. Log in to the Defense Center.
9. Select Help > About and confirm that the software version is listed correctly: 

Version 5.2.0.2.

10. Verify that the appliances in your deployment are successfully communicating 

and that there are no issues reported by the health monitor.
