When deploying the Client Extensions using a "push" method, ie Group Policy Object (GPO), the install does not run completely Silent. The Client install is based on a Microsoft Installer (MSI) file which is executed by MSIEXEC.exe and it has various switches available to control the installation process.  In order to push an MSI Install using "Quiet mode", it is necessary to use the /q switch so that the install will not require user interaction.  Due to the number of available switches for MSIEXEC.exe, it is recommended to contact Microsoft for implementing an MSI Install using other customized switches.
