Windows agent installation and uninstallation options

Many options are available when you install and uninstall Windows agent software on your host machines.

Note

If you are deploying the Endpoint Security (HX) software in a VDI environment, Trellix recommends deploying in a persistent or semi persistent VDI environment. See Agent installation considerations.

Some options are provided by the Windows msiexec executable; others are provided by Trellix extensions of msiexec.

Specify these options when you initiate the installation. A standard installation setup wizard will perform the installation, using the options you specify.

Standard msiexec options you might find useful are listed in the following table. For complete information about all standard msiexec options, see your Microsoft documentation or enter msiexec /h at a command prompt.

Option	Description
`/i`	Install or configure the software. Specify the name of the installation `*.msi` executable file.
`/x`	Uninstall the software installed by the named installation `*.msi` executable file. If the Removal Protection Password is enabled, you must enter this password to authorize the Endpoint Security (HX) uninstall process by appending the `/x` command with `UNINSTALL_PASSWORD=<password>`. Only authorized users can uninstall the agent software. See Configuring the agent removal protection password for more information.
`/qn /qb /qr /qf`	Set the user interface level for the install or uninstall process: `/qn`: no user interface `/qb`: basic user interface `/qr`: reduced user interface `/qf`: full user interface
`/quiet`	Install the product in quiet mode.
`/l*v`	Enable agent logging for the install or uninstall process.
`/norestart`	Do not restart the system after the installation is complete.

This section explains how to use the Trellix extensions to the msiexec executable for TrellixEndpoint Security Agent (HX) installations.
