Deploying MVC4 website containing ADO.NET Entity Data Model

Question

I've created an MVC4 website containing an ADO.NET Entity Data Model (linq to entities) but am getting the following error when deploying to a server

[ArgumentException: Unable to find the requested .Net Framework Data Provider.
   It may not be installed.]
System.Data.EntityClient.EntityConnection.GetFactory(String providerString) +251

The DB is SQL Server (System.Data.EntityClient) and this works fine from my laptop. The server is Windows 2008 with .NET 4 installed. Does anyone know what I am missing?

Doh, the Application Pool needed to be "Enable 32bit Application = true"

Glad it works, but that sounds wrong to me - why would you only be able to run this in 32-bit? SqlClient is provided by Microsoft so should exist as 64-bit already. Is the EF install really 32-bit only?
