2.2 Uninstalling ZENworks from a Windows Managed Device

When uninstalling the ZENworks Agent from a managed device, please be aware of the following:

If an uninstall password is required (the Require an uninstall password for the ZENworks Agent option is enabled), you must know the password and supply it during the uninstall process.

The agent uninstall password is set in ZENworks Control Center at either the zone level (Configuration > Management Zone Settings > Device Management > ZENworks Agent > Agent Security), folder level (Devices > Managed > folder Details > Settings > Device Management > ZENworks Agent > Agent Security), or device level (Devices > device > Settings > Device Management > ZENworks Agent > Agent Security).
If the device has a ZENworks Full Disk Encryption policy applied, remove the Disk Encryption policy assignment before uninstalling the ZENworks Agent. This decrypts the device’s disks prior to the software removal and is a recommended best practice to ensure successful disk decryption.
If the device has a ZENworks Endpoint Security Management Data Encryption policy applied, have the user decrypt files by moving them from Safe Harbor folders and encrypted removable storage devices to non-Safe Harbor (unecrypted) folders on the computer. After the user is finished decrypting files, remove the Data Encryption policy assignment from the device and then uninstall the ZENworks Agent.

To uninstall ZENworks from a Windows managed device:

At a command prompt, run the following command to launch the ZENworks uninstall program:

zenworks_installation_directory\novell\zenworks\bin\ZENworksUninstall.exe

To see the list of uninstall options, run ZENworksUninstall.exe --help

Click Next, then follow the prompts to uninstall the ZENworks software. Refer to the information in the following table if you have questions about any of the uninstall options.

This screen is displayed only if you have logged in to the Managemetn Zone in order to unregister the device during uninstallation of the ZENworks software.

Select the Uninstall the ZENworks Agent and unregister the device from the zone option. Click Next to confirm the operation.

Components To Be Retained

Select any of the following components that you do not want uninstalled:

ZENworks Pre-Agent: Leaves the ZENworks Pre-Agent installed on the device, but removes all other ZENworks component. By default, this is not selected.

Leaving the ZENworks Pre-Agent on the device allows it to respond to Advertised discovery requests and ZENworks Ping requests if an IP-based discovery is performed on the device.

To remove the ZENworks Pre-Agent from a device after ZENworks has been uninstalled from the device, see Removing the ZENworks Pre-Agent from a Device in the ZENworks Agent Reference.
CASA: Leaves the Novell CASA (Common Authentication Services Adaptor) software installed. By default, this is selected because CASA can be used by other software programs.

IMPORTANT:If you have ZENworks Pre-agent installed on a device, and you want to install an earlier version of it, you need to first uninstall the existing version of ZENworks Pre-agent, along with the installed version of CASA.

If the ZENworks Agent requires an uninstall password, enter the password when prompted.

You must enter the password within 5 minutes of the prompt being displayed. Otherwise, the uninstall process times out and you must restart the process.
When the uninstall is finished, the Uninstallation Status dialog box is displayed. Review the status comments, make sure the Restart Now option is selected, then click Finish.

If desired, you can deselect the Restart Now option and reboot the device at a later time to complete uninstallation of the files and folders that were not able to be removed.
After the device reboots, perform the following tasks to ensure that ZENworks is completely removed:
- ZENworks Log Files: Log files are purposely left here for your review. You can manually delete the ZENworks_installation_path\Novell\ZENworks directory at any time.
- CASA: If you retained CASA during the uninstallation, and want to remove it later, you can do it from Windows Add/Remove Programs. If the c:\program files\novell\casa directory exists even after you select to uninstall CASA, you can manually delete it.
