title: .NET 4.0 project on IIS 7.0
body: <p>We have an IIS 7.0 server running a .NET framework 3.5, MVC2 application.  We now need to run a .NET Framework 4.0, MVC3 app on this same server and have both apps run from the same server.</p>
  
  <p>Whenever I try to browse the 4.0/MVC3 website after deploying it, I get a 404.0 error that it can't find C:\inetpub\wwwroot\MYNEWAPP\Error</p>
  
  <p>This project works perfectly fine on a local machine.  I feel like I've been down every path (including the ones on this website), but still can't get it fixed.  The older website on this same server still works fine.  I believe I have the pool set up correctly also.</p>
  
  <p>Where can I look next?  I can't find permission problems or anything like that.  </p>
  
  <p>Please help.
  Thanks</p>
