Could not create the driver from NHibernate.Driver.OracleDataClientDriver (with copy local set to true)
===

I even added to app.config this little piece of config:

    <qualifyAssembly partialName="Oracle.DataAccess"
                 fullName="Oracle.DataAccess,
                                Version=2.112.2.0,
                               Culture=neutral,
                               PublicKeyToken=89b483f429c47342" />
        </assemblyBinding>

... with no success. What could be wrong?
Also, just to be sure that my app.config is feng shui, here it is:

    <?xml version="1.0"?>
    <configuration>
      <configSections>
        <section name="hibernate-configuration"
        type="NHibernate.Cfg.ConfigurationSectionHandler, NHibernate"/>
      </configSections>
      <hibernate-configuration xmlns="urn:nhibernate-configuration-2.2">
        <session-factory>
          <property name="show_sql">true</property>
          <property name="dialect">NHibernate.Dialect.Oracle10gDialect</property>
          <property name="connection.driver_class">
            NHibernate.Driver.OracleDataClientDriver
          </property>
          <property name="connection.connection_string_name">
            GuitarStore2
          </property>
          <property name="connection.provider">
            NHibernate.Connection.DriverConnectionProvider
          </property>
        </session-factory>
      </hibernate-configuration>
      <connectionStrings>
        <add name="GuitarStore"
        connectionString="****************"/>
      <add name="GuitarStore2"
        connectionString="****************"/>
      </connectionStrings>
      <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">
          <qualifyAssembly partialName="Oracle.DataAccess"
                 fullName="Oracle.DataAccess,
                                Version=2.112.2.0,
                               Culture=neutral,
                               PublicKeyToken=89b483f429c47342" />
        </assemblyBinding>
      </runtime>
    </configuration>

For the record, I am using the latest Nhibernate (3.3.1), on .NET 3.5, under Windows 7 64 bit. And, with the exact same project, I encounter no exceptions on another machine, but with Windows XP.
