.NET 4.0 project on IIS 7.0

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.

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

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.

Where can I look next? I can't find permission problems or anything like that.

Please help. Thanks

.net 3.5 and 4 can co-exist just fine. However, you need to make sure the worker process is set to use the correct framework. .net 4 requires the 4.0 runtime and .net 3.5 requires the v2.0 runtime.
