Desktop Central Agent uninstall restriction does not work

Desktop Central Agent uninstall restriction does not work

Hi all, 

i am new to Desktop Central.

Currently my setup involves the Desktop Central Server running in a machine in my LAN (without AD), and the installing the agent on all client machines in the LAN. 

In Agent--->Agent Settings and Security Settings I have enabled "Restrict users from Uninstalling the Agent from Control Panel". However when I download and install the agent after applying the above, I am still able to uninstall the agent from the control panel. 

Am I missing something obvious? 

Thanks in advance.
