How to Perform a Silent Install of SQL Server (or SQL Express)

I needed to install SQL Server Express 2016 silently, but the documentation out there wasn’t the best. The trick to installing this silently is to create a ConfigurationFile.ini and then reference that during the install.

Luckily for us, the installer creates the Configuration File for us.

Download SQL Server

I’ve only tested this using the offline installer (roughly 400MB), not the bootstrapped version (4MB). Start by downloading the SQL Server installer. For this guide, I’m using the 2016 Full Offline installer, which can be found here:

Run the installer

After that, you’ll want to run the installer on the package that you downloaded:


Please take note that /Action parameter is required. Setting /UImode to Normal will present every dialog box that exists in the installer (even ones that do not apply to Express). Normal is the default value for non-express editions.

Go through the various installation steps using the GUI until you get to the “Ready to InstalL” step. Once here, if you look at the bottom of the GUI window, it will give you path to the Configuration File that the setup created.

A few more changes

A few things you should know about your ConfigurationFile.ini:

  • You must add IACCEPTSQLSERVERLICENSETERMS="True" to your file manually. The installer does not create this for you, and the install will fail without this.
  • Optionally, you can specify the SA account password by referencing SAPWD="ENTER_YOUR_PASSWORD".
  • To install silently, you need to set QUIET="True". You cannot have both QUIET and QUIETSIMPLE both set to True. It’s one or the other.
  • Also, if you want to install silently, you must remove or comment out UIMODE="Normal" in the file.

A sample configuration

This is what my configuration looked like. Feel free to copy it if you’d like:

;SQL Server 2016 Configuration File

; Specifies a Setup work flow, like INSTALL, UNINSTALL, or UPGRADE. This is a required parameter. 


; Detailed help for command line argument ROLE has not been defined yet. 


; Specifies that SQL Server Setup should not display the privacy statement when ran from the command line. 


; By specifying this parameter and accepting Microsoft R Open and Microsoft R Server terms, you acknowledge that you have read and understood the terms of use. 


; Use the /ENU parameter to install the English version of SQL Server on your localized Windows operating system. 


; Setup will not display any user interface. 


; Setup will display progress only, without any user interaction. 


; Parameter that controls the user interface behavior. Valid values are Normal for the full UI,AutoAdvance for a simplied UI, and EnableUIOnServerCore for bypassing Server Core setup GUI block. 

; UIMODE="Normal"

; Specify whether SQL Server Setup should discover and include product updates. The valid values are True and False or 1 and 0. By default SQL Server Setup will include updates that are found. 


; If this parameter is provided, then this computer will use Microsoft Update to check for updates. 


; Specifies features to install, uninstall, or upgrade. The list of top-level features include SQL, AS, RS, IS, MDS, and Tools. The SQL feature will install the Database Engine, Replication, Full-Text, and Data Quality Services (DQS) server. The Tools feature will install shared components. 


; Specify the location where SQL Server Setup will obtain product updates. The valid values are "MU" to search Microsoft Update, a valid folder path, a relative path such as .MyUpdates or a UNC share. By default SQL Server Setup will search Microsoft Update or a Windows Update service through the Window Server Update Services. 


; Displays the command line parameters usage 


; Specifies that the detailed Setup log should be piped to the console. 


; Specifies that Setup should install into WOW64. This command line argument is not supported on an IA64 or a 32-bit system. 


; Specify a default or named instance. MSSQLSERVER is the default instance for non-Express editions and SQLExpress for Express editions. This parameter is required when installing the SQL Server Database Engine (SQL), Analysis Services (AS), or Reporting Services (RS). 


; Specify the root installation directory for shared components.  This directory remains unchanged after shared components are already installed. 

INSTALLSHAREDDIR="C:Program FilesMicrosoft SQL Server"

; Specify the root installation directory for the WOW64 shared components.  This directory remains unchanged after WOW64 shared components are already installed. 

INSTALLSHAREDWOWDIR="C:Program Files (x86)Microsoft SQL Server"

; Specify the Instance ID for the SQL Server features you have specified. SQL Server directory structure, registry structure, and service names will incorporate the instance ID of the SQL Server instance. 


; TelemetryUserNameConfigDescription 


; TelemetryStartupConfigDescription 


; Specify the installation directory. 

INSTANCEDIR="C:Program FilesMicrosoft SQL Server"

; Agent account name 


; Auto-start service after installation.  


; CM brick TCP communication port 


; How matrix will use private networks 


; How inter brick communication will be protected 


; TCP port used by the CM brick 


; Startup type for the SQL Server service. 


; Level to enable FILESTREAM feature at (0, 1, 2 or 3). 


; Set to "1" to enable RANU for SQL Server Express. 


; Specifies a Windows collation or an SQL collation to use for the Database Engine. 


; Account for SQL Server service: DomainUser or system account. 


; Set to "True" to enable instant file initialization for SQL Server service. If enabled, Setup will grant Perform Volume Maintenance Task privilege to the Database Engine Service SID. This may lead to information disclosure as it could allow deleted content to be accessed by an unauthorized principal. 


; Windows account(s) to provision as SQL Server system administrators. 


; The number of Database Engine TempDB files. 


; Specifies the initial size of a Database Engine TempDB data file in MB. 


; Specifies the automatic growth increment of each Database Engine TempDB data file in MB. 


; Specifies the initial size of the Database Engine TempDB log file in MB. 


; Specifies the automatic growth increment of the Database Engine TempDB log file in MB. 


; Provision current user as a Database Engine system administrator for %SQL_PRODUCT_SHORT_NAME% Express. 


; Specify 0 to disable or 1 to enable the TCP/IP protocol. 


; Specify 0 to disable or 1 to enable the Named Pipes protocol. 


; Startup type for Browser Service. 


; Accept License Agreement. Silent install fails if this is not true.


; SysAdmin Password



cd to the subdirectory where all your files were extracted. You’ll then run the following command:

.setup.exe /ConfigurationFile=ConfigurationFile.ini

That’s it! Enjoy.
