Oracle.DataAccess.dll not loading using C #

I am having a problem loading the oracle.dataaccess file. Here is the message I get:

Failed to load file or assembly "Oracle.DataAccess, Version = 2.112.1.0, Culture = neutral, PublicKeyToken = 89b483f429c47342" or one of its dependencies. An attempt was made to download a program with the wrong format.

I have the following entries in my web.config for this.

<add assembly="Oracle.DataAccess, Version=2.112.1.0, Culture=neutral,
  PublicKeyToken=89b483f429c47342"/>

Under assemblies

and

<dependentAssembly>
  <assemblyIdentity name="Oracle.DataAccess" publicKeyToken="89b483f429c47342"
    Culture="neutral" />
  <BindingRedirect oldVersion = "2.112.1.2" newVersion = "2.112.1.0" />
</dependentAssembly>**

I am developing on Visual Studio 2008 on a Windows Vista machine. I have an IIS 7.0 application pool for 32-bit applications, and my platform for this project is x86 instead of "Any processor."

I'm still trying to figure out what exactly is wrong in this case.

, :

1)The project reference pointed to OracleDataAccess.dll , version 64 bit.
2)In the project properties -> Build -> Platform target : x64. So when you 
select x64, Prefer 32-bit option would be unchecked automatically. Then I 
did re-build of the project and deployed.
