Uninstalling the Update

To uninstall the update:

1. Read and understand 

2. On the managing Defense Center, make sure that the appliances in your 

deployment are successfully communicating and that there are no issues 

reported by the health monitor.

3. On the managed device, view the task queue (System > Monitoring > Task 

Status) to make sure that there are no tasks in progress.
Tasks that are running when the uninstallation begins are stopped, become 

failed tasks, and cannot be resumed; you must manually delete them from 

the task queue after the uninstallation completes. The task queue 

automatically refreshes every 10 seconds. You must wait until any 

long-running tasks are complete before you begin the uninstallation.

4. Select System > Updates.

The Product Updates tab appears.

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

to remove, 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 device reboots. Before the 

uninstallation completes, the web interface may become unavailable and the 

device 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.

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

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

behavior.

7. Log in to the device.
8. Select Help > About and confirm that the software version is listed correctly: 

Version 5.3.

9. On the managing Defense Center, verify that the appliances in your 

deployment are successfully communicating and that there are no issues 

reported by the health monitor.
