Oracle Connection error 'Oracle.DataAcess.Client' Not Installed

I have been using PBI Desktop RS with an On-Premesis server for about a year now. My company is now moving to E5 licences so I'd like to start using PBI Desktop with cloud based reporting.


With Desktop RS I have no issues connecting to an oracle db, but with PBI Desktop I get the following error.


"The recommended provider ('Oracle.DataAccess.Client') is not installed. You can continue with your current provider, however it has been deprecated and may not work properly."


I can click ok and enter the server details on the next screen but when attempting to connect get the error....


Details: "The provider being used is deprecated: 'System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.'. Please visit to install the official provider."


My understanding is that I already have this otherwise Desktop RS wouldn't work!?


The Desktop RS and Desktop versions are different as dictated by the managers of the RS.


Desktop RS = Version: 2.76.5678.1521 64-bit (January 2020)

Desktop = Version: 2.84.802.0 64-bit (August 2020)


My ODAC version should be ODAC122011_x64


Anyone able to shed any light on this?


Thanks all, I removed everything relating to Oracle and reinstalled.


Now working ok.

Hi @mdex 

You will need the latest OBDC driver. To do that you will have to install / update your oracle client. There are upgrades releases to the way a driver connects so updating oracle client will help you resolve this issue.

Hope it resolves your issue?

@mdex , Not very clear. as the desktop version is higher is needs the latest version of the oracle driver, that is what I can get from it.
