Error pulling data VIA Denodo ODBC connection

Hi vibhav92 ,

There's a document talking about this similar error.

(Class not registered) error when updating PowerPivot data - Office | Microsoft Learn

This issue generally occurs under the following scenarios:

• You try to update the data with the most current data from the back-end server by using the Refresh All option in the Refresh menu.
• You try to import data by using one of the connections under the Existing Connection option in the Design tab.

This behavior is by design. It occurs when the provider that is defined for the data connection for PowerPivot data doesn't exist on your system.

Best Regards,
