The following link: Install SQL Server 2014 from the Command Prompt
states: The /QS switch only shows progress, does not accept any input, and displays no error messages if encountered. This is incorrect. The /QS switch shows the Choose Directory for Extract Files dialog with Ok, Cancel, and Browse buttons. The user must click on one of these buttons to continue. This is a problem for me because I am installing SQL Server 2014 Express using the InstallShield Install Pre-requisites functionality. I am using the /QS switch instead of the /Q switch because it takes several minutes to install SQL Server 2014 Express and I want the user to be able to see activity during the installation. Note: The /Q switch does suppress this dialog, but it suppresses all dialogs. The change I would like is to be able to use the /QS switch, but suppress the Choose Directory for Extracted Files dialog requirement for user input. Thank you.
