You must install Windows Installer 3.1 on the computers that contain and run earlier versions of Windows Installer. You can display Windows Installer versions by running msiexec /? in a command prompt. Windows Installer 3.1 or later is required for the GPO installation package. On the computers that require the installation of Windows Installer 3.1 or later, how you install it is up to you.
Restricted users cannot run Windows Installer 3.1, and restricted users with elevated privileges cannot run Windows Installer 3.1. Restricted users are set with the local security policy.
One way to install Windows Installer is with a GPO computer startup script. When computers restart, startup scripts execute before the GPO launches the installation. If you use this approach, be aware that the startup script executes and reinstalls Windows Installer every time the computer is restarted. If you install it in silent mode, however, users experience a slight delay before they see the logon screen. Symantec client software is only installed one time with a GPO.
