Uncertified connector message
Problem
When the Power BI Desktop is opened and the Dremio connector is selected in Get Data, the following pop-up message appears:

This error occurs because there is a Power BI connector installed locally.
note
We are moving away from having connectors installed locally. Instead, you should use the certified connectors that are available as part of the desktop or gateway installations.
Solution
Check to see if you have a Dremio.mez file in the C:\Users\{Your Username}\Documents\Power BI Desktop\Custom Connectors
folder. If so, you should remove it.
