Asp.net-mvc – ASP.NET MVC – Elmah not working and returning 404 page for elmah.axd

I'm trying to use elmah for my MVC application and I've followed the steps on the wiki: http://code.google.com/p/elmah/wiki/MVC , but even so when trying to access myapp/elmah.axd the page:

404 – File or directory not found.

Anyone could help me please?
