Re: Oracle DirectQuery Error

Hello Squiles,


If you downloaded Power BI Desktop from the Microsoft Store, you might be unable to connect to Oracle databases because of an Oracle driver issue.


To address the issue, do one of the following:

  • Download Power BI Desktop from instead.

  • If you want to use the version from the Microsoft Store: on your local computer, copy oraons.dll from 12.X.X\client_X into 12.X.X\client_X\bin. The X represents version and directory numbers.

If that does not help I woud uninstall the ODAC components and install them again. Please be sure to have the right Bit-Version.

For the installation of the ODAC components may I provide you this link

Have a nice day!
