About configuring MSI command strings
Symantec Endpoint Protection installation software uses Windows Installer (MSI) 3.1 or later packages for installation and deployment. If you use the command line to deploy a package, you can customize the installation. You can use the standard Windows Installer parameters and the Symantec-specific features and properties.
To use the Windows Installer, elevated privileges are required. If you try the installation without elevated privileges, the installation may fail without notice.
For the most up-to-date list of Symantec installation commands and parameters, see the article: MSI command line reference for Symantec Endpoint Protection.
The Windows Installer advertise function is unsupported. Setaid.ini-specified features and properties take precedence over MSI-specified features and properties. Feature and property names in MSI commands are case-sensitive.
