title: Sandcastle Help File Builder - how to change msbuild path?
body: <p>I'm trying out Sandcastle Help File Builder.  If I run the build from the gui I'm getting this error:</p>
  
  <p>C:\Program Files\MSBuild\Microsoft\VisualStudio\v9.0\WebApplications\Microsoft.WebApplication.targets" was not found</p>
  
  <p>This is because it's in C:\Program Files (x86) directory.</p>
  
  <p>So how do I configure to use that dir instead?</p>
