[Options] -I, -Install willInstall [Description] 
(Deployment manifests only) Indicates whether or not the ClickOnce application should install onto the local machine, or whether it should run from the Web. Installing an application gives that application a presence in the Windows Start menu. Valid values are "true" or "t", and "false" or "f". If unspecified, the default value is “true”. If you specify the –MinVersion option, and a user has a version less than -MinVersion installed, it will force the application to install, regardless of the value you pass to -Install.
