title: Free installer that can install prequisites (.net framework, sql server)
body: <p>i've been googleing a bit, but can't fin anything useful.
  I need a recomendation for a free installer for a c# app. The thing is, i'm using visual studio express edition and i'm makin a commercial product.
  The express edition does not support the installer.
  Basically, i need the installer to check for the .net frameword and sql server installed on the client computer. If it's there, install my app, if not, install that first and then my app.</p>
  
  <p>Any advice / tip would be useful!</p>
