After successfully installing or upgrading to Endpoint Protection (SEP) 14 client without the firewall component, the SEP installer prompts for a restart. This happens regardless of whether the installation settings for the installation package were configured to not prompt for a reboot.
Updates to the SEP 14 installer cause it to request a restart before the restart policy from the installation package loads. The installer is using the default restart prompt settings instead of the custom settings included with the installation package.
This issue is fixed in SEP 14 Maintenance Patch 1 (14 MP1). For more information see how to download the latest version of Symantec Endpoint Protection.
