title: setup project .net 4 prerequisite
body: <p>I added .NET Framework 4 to my setup package as a prerequisite. When installing this package, an error reports that installing .NET 4 requires WIC "windows imaging component", which I've also added as a prerequisite.</p>
  
  <p>But the installation failed due to a newer version of this component being already installed.</p>
  
  <p>I want to ask how to check whether this WIC is installed or not and skip installing it when there is a newer version?</p>
