I found that there was a registry entry that was giving me grief with the install, and here are the instructions that I used to fix the problem.
CLI Install: Command Line Install Options are detailed at Install using the command line at Citrix Docs.
For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only: Specify how frequently the following Configuration Manager clients download client policy: When you configure this setting as True or Yes, and Configuration Manager has discovered the user, Configuration Manager clients on computers receive applications and programs that are targeted to the logged on user.
For more information about how to discover users, see the Configure Active Directory Discovery for Computers, Users, or Groups section in the Configuring Discovery in Configuration Manager topic.
Client settings for devices: Specify the maximum transfer rate in (Kbps) that will be used by Configuration Manager clients when outside of the specified BITS throttling window.Before you begin to create automatic deployment rules, make sure that you have configured Configuration Manager software updates.For more information, see Software Updates in Configuration Manager.I had a Windows 2008 server that I was attempting to install the Symantec Endpoint client on, but the client would not install, and the following message was left in the event log: Symantec Endpoint Protection (SEP) Installation fails with the following error “Symantec Endpoint Protection has detected that there are pending system changes that require a reboot.Please reboot the system and rerun the installation.” I rebooted the server and then tried to install the client again, but the same error would appear.
