title: Selecting target platform for visual studio 2015 installer project
body: <p>I have created a installer project in visual studio 2015. Success fully build the application and installed in my system(I'm using Windows 10 64-bit). But when I try to install the same in a 32 - bit OS, I'm getting the error message saying <strong>"installation package is not supported by this processor"</strong>. I have checked the properties of the project But there is nothing related to this. All  projects( I have 4 projects) inside the solution are build with <code>AnyCPU</code> mode. </p>
  
  <p>When I open the configuration manager from there is options for choosing the configuration and platform for other projects, but we cannot choose the platform for the setup project. I'm attaching the screenshot.</p>
