Hi @mbq ,

This error usually means the OLE DB provider for Power BI isn’t properly installed or registered on your machine. The message "Class not registered" is a strong hint that Windows can’t find the required COM component.

Here’s what you can try:

• Make sure you’ve installed the latest version of Power BI Desktop from the official Power BI download page.
• If you're using a custom or older OLE DB provider, you might need to manually install or re-register it. You can do that by running regsvr32 from an elevated command prompt.
• Also double-check if you're on a 64-bit or 32-bit system and that the provider matches that architecture.

Let me know what provider you're trying to use exactly, I can help you find the right installer if needed.

If my response resolved your query, kindly mark it as the Accepted Solution to assist others. Additionally, I would be grateful for a 'Kudos' if you found my response helpful.
