Error connecting Power BI to Oracle RAC

Hello guys.

I'm trying to connect Power BI to Oracle RAC, but it's returning an error message stating that the "System.Data.OracleClient" provider being used is obsolete.


Do you know how I can solve the problem?

I am having the same issue after installing the latest Windows Update at the beginning of the week. Last week, I could successfully connect to Oracle using 32 bit Power BI Desktop with the 32 bit Oracle Data Access Components.


Is it now not possible to connect to an Oracle Database using 32 bit Power BI Desktop at all?!
