The ExecMethod fails with 0x80041002 WBEM_E_NOT_FOUND only in Vista.
The code works fine in XP.

IWbemClassObject* pClass = NULL;
hres = service->GetObject(ClassName, 0, NULL, &pClass, NULL);

IWbemClassObject* pInParamsDefinition = NULL;

IWbemClassObject* pClassInstance = NULL;
hres = pInParamsDefinition->SpawnInstance(0, &pClassInstance);

// Create the values for the in parameters
VARIANT varCommand;
varCommand.vt = VT_I4;
varCommand.iVal = nRestoreSequenceNumber_;

// Store the value for the in parameters
hres = pClassInstance->Put(L"SequenceNumber", 0, &varCommand, 0);

// Execute Method
IWbemClassObject* pOutParams = NULL;
hres = service->ExecMethod(ClassName, MethodName, 0, NULL, pClassInstance, &pOutParams, NULL);

Any ideas what could be wrong?

Thanks

I have a problem with ExecMethod for Calling CreateSnapshot, My `pOutParams.ResultingSnapshot` is returned as NULL even when the snapshot/checkpoint is created. Any clue about this?

Below is the text of pOutParams
instance of __PARAMETERS
{
Job = "\\\\WIN-ADU8U45M3SN\\root\\virtualization\\v2:Msvm_ConcreteJob.InstanceID=\"FF983E2C-2BC4-4FF1-822B-93922290B631\"";
ResultingSnapshot = NULL;
ReturnValue = 4096;
};
