Error Refreshing in Desktop
I don't know how to resolve this; please help
Hi mbq,
Could you please try with below action points.- Make sure your using latest version of Power BI desktop application. https://apps.microsoft.com/detail/9NTXR16HNW1T?hl=en-us&gl=IN&ocid=pdpshare
- Clear Power BI cache and credentials
a. Go to File → Options and settings → Data source settings
b. Clear credentials for the failing data source.
c. Try reconnecting.
- Check your query or data source
a. If you're using custom connectors or scripts, one might be calling a missing provider.
b. Try simplifying the query or testing other connections
- Try re-register the OLE DB provider manually

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.
