Can't get ELMAH to works with ASP.NET MVC2 on IIS7.5 - asp.net-mvc-2

Question

I try to use ELMAH on my ASP.NET MVC2 application, it works fine on the test server (Casini x86) while using the x86 version, but when I deploy it on the production server with the x86_64 version, I get a 404 error when I try to access "elmah.axd" and no errors are logged on IIS (but they are logged in Casini)
Here is my Web.config
<?xml version="1.0" encoding="utf-8"?>

The URL used on the production server is: http://xxxx/IronViperWebInterface/elmah.axd
and on Casini : http://localhost:xxxx/elmah.axd
I tried to change
<add verb="POST,GET,HEAD" path="elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
to
<add verb="POST,GET,HEAD" path="IronViperWebInterface/elmah.axd" type="Elmah.ErrorLogPageFactory, Elmah" />
but that don't change anything.
I can't find the problem..
Any idea please ?
Thank you
