You can use the silent installation feature to automate the installation or upgrade of Symantec Protection Engine. You can use the silent installation feature when you install or upgrade multiple Symantec Protection Engines that have identical input values.
In Solaris and Linux, you can capture the required input values for installation in a response file. You can use the response file for subsequent installations to read in the values so that the installations are silent. This response file frees you from having to repeatedly supply input values for each installation.
In Windows you provide all of the information on the command-line first, and then run the installation silently.
