The registry should contain a path to this file under the following key:
HKEY_CLASSES_ROOT\TypeLib\{FCFB3D2E-A0FA-1068-A738-08002B3371B5}\6.0\9\win32If the key is missing or pointing to a location where the file cannot be found, Visual Basic returns the preceding error message during startup.

Resolution
The sample code that appears on these MSDN Web sites contains the following code that may cause you to receive the System.Messaging.MessageQueueException error message.
Microsoft Visual Basic .NET

myQueue.Send(“My Message Data.”, New _MessageQueueTransaction())Microsoft Visual C# .NET

myQueue.Send(“My Message Data.”, newMessageQueueTransaction());Microsoft Visual C++ .NET

myQueue->Send(S”My Message Data.”, new MessageQueueTransaction());You receive the error message because the call to the myQueue.Send method uses a MessageQueueTransaction object without starting a transaction. Additionally, even if you start a transaction before calling the myQueue.Send method, your application may wait indefinitely to receive the sent message. However, your application does not receive a sent message unless the corresponding transaction is committed.
Note The MessageQueue.Send(Object, MessageQueueTransaction) method applies only to transactional queues. Therefore, you receive the error message that is mentioned in the “Symptoms” sectiononly if you use transactional queues.
