I got this error when trying to browse a cube. This happen once I installed MS SQL SP 2. From what i found, most likely the OWC component installation became corrupted. To solve this, just install OWC again. This works for me.

    Hi bhavin,

    I believe this error doesn’t relate to my solution. This is a generic error occur in your VB project where compiler does not recognize the class used in your project. Do check your project reference and make sure all sources are reference correctly.
