Oracle client error

When I tried to connect to Oracle DB from Power BI, I get this 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.

 

It used to work when I had Power BI 32-bit version with ODTwithODAC122011 Oracle client on Windows version 1709. But my laptop had to be re-installed with Windows 1903 version and now this combination does not work anymore. I also tried the 64-bit with ODAC122011_x64 Oracle client and it also does not work. Both Power BI versions I have are the latest versions that can be downloaded from the website.

 

Please help!

In the installation directory, there is read me. Please make sure based on that you do all path entry to Env variables.

 

I installed in d:/oracle the client. I have given following path entries

Hi Amit,

 

Thanks for your reply. Under my Oracle folder, I don't see the files and subfolders you mention. I should be able to see them before I set the env variables, right?

 

Also I didn't have to do this when I had Windows version 1709. It just works after installing the client.
