DMM 4070 interchangeability

[redwaterlily]

How do I achieve interchangeability for DMM 4070?

In C# code, I wrote:

using Ivi.Dmm;

using Ivi.Driver;

IIviDmm iviDmmSession = IviDriver.Create<IIviDmm>("MyDMMLogical", false, false);

where the logical name point to this software module in IviConfigurationStore.xml:

<IviSoftwareModule id="p181">
 <Name>NationalInstruments.ModularInstruments.NIDmmWrapper 1.0 Fx40</Name>
 <Description>National Instruments Dmm .NET Class Driver</Description>
 <DataComponents/>
 <ModulePath/>
 <Prefix>NIDmm</Prefix>
 <ProgID/>
 <SupportedInstrumentModels/>
 <PhysicalNames/>
 <PublishedAPIs>
  <IviPublishedAPI idref="p7"/>
  <IviPublishedAPI idref="p11"/>
 </PublishedAPIs>
 <AssemblyQualifiedClassName>NationalInstruments.ModularInstruments.NIDmm.NIDmm, NationalInstruments.ModularInstruments.NIDmm, Version=1.0.40.146, Culture=neutral, PublicKeyToken=DC6AD606294FC298</AssemblyQualifiedClassName>
 <ModulePath64/>
</IviSoftwareModule>

But I got this error when creating the iviDmmSession:

IviSessionFactory: An instance of the specific driver referenced by the driver session name could not be created, or did not support the specified type.
Specific driver (software module): NationalInstruments.ModularInstruments.NIDmmWrapper 1.0 Fx40
Class name: NationalInstruments.ModularInstruments.NIDmm.NIDmm, NationalInstruments.ModularInstruments.NIDmm, Version=1.0.40.146, Culture=neutral, PublicKeyToken=DC6AD606294FC298

Please help me out. Thanks.
