title: When installing setup prerequisite is not asking for SQL Server 2008 Express
body: <p>I have an application which has SQL Server 2008 Express as a prerequisite. It is working fine on Windows XP and Windows 7 Home Basic. But when we install it on a Windows 7 Professional machine it asks for .Net framework but not ask for SQL Server 2008 Express.</p>
  
  <p>I do not understand what is wrong in setup.</p>
