Unable to connect to SAP BW with Power BI

Hi,

 

I am trying to connect to the SAP WB via Power BI but i have this error:


Details: "This error could've been the result of provider-specific client software being required, but missing on this computer. To download client software for this provider, visit the following site and choose the 64-bit (x64) version of, at minimum, 'SAP .NET Connector 3.0.0.42 / SAP .NET Connector 3.1.0.42': "

 

I tried to install .Net connector previous versions or new ones but nothing is happening eah time is the same error.
I saw in this forum that they choose the option 3 but still nothing with me.

 

please i need your help because I am stuck over here.

 

in advance thank you very much
