Asp.net mvc 4 on iis6: "The page cannot be found"

Question

I am having trouble getting ASP.Net MVC 4 running on IIS 6.

First, i got "Directory listing denied" and that already solved after I setup extensionless urls based on Phil Haack's blog post: ASP.NET MVC on IIS 6 Walkthrough.

Now, I'm getting "The page cannot be found" 404 page.

It's a simple ASP.Net Web Api project in MVC 4 beta.

Answer 1

Under application configuration, I insert wildcard extension mapping to:

c:\windows\microsoft.net\framework\v4.0.30319\aspnet_isapi.dll

But I forgot to un-check on Verify that file exists checkbox.
