After downloading Zimbra Desktop there are two ways to install it. For end-users it is a matter of double clicking it and going through the set-up wizard.
For administrators looking to deploy Zimbra Desktop in a corporate environment there is a silent installation switch. By using the switch you can script the installation of Zimbra Desktop without end-user interaction.
For silent installation the /S switch can be used, for example:
"Zimbra Desktop Setup 0.0.1.exe" /S
A similar /S switch can be used for un-installation, for example:
"Uninstall Zimbra Desktop.exe" /S
