title: How to install sql server 2008 r2 express silently using installshield
body: <p>I have created a C# Windows application and used SQL Server 2008 R2 for database. So I need to install SQL Server on my client's machine to run my application.</p>
  
  <p>For this I have created a setup using Installshield and added prerequisites SQL Server. </p>
  
  <p>But the problem is: I need to install it silently so user doesn't have to configure it. I have tried a command line code but it not working, it's showing installing SQL Server, but it does not really get installed. </p>
  
  <p>Code I have tried :-</p>
  
  <pre><code>SQLEXPRWT_x86_ENU.exe /q /Action=Install /Hideconsole 
       /Features=SQL,Tools /InstanceName=SQLExpress 
       /SQLSYSADMINACCOUNTS="Builtin\Administrators" 
       /SQLSVCACCOUNT="NT AUTHORITY\Network Service" /SQLSVCPASSWORD="a123"
  </code></pre>
