Hello Hedi,

thank you for the detailed description. Did you check if SAP NW RFC SDK for Windows platform is installed, or for another platform perhaps? It is the most common installation issue.

To check, open the Windows console and cd to c:\nwrfcsdk\bin. Run the startrfc.exe in that folder, with -v argument. The output should be like below (tested on Mac ARM)

cd $SAPNWRFC_HOME/bin
./startrfc -v
RfcLogWrite: could not open /usr/local/sap/nwrfcsdk/bin/./dev_rfc_46095.log. Trace directory set to ./
NW RFC Library Version: 750 Patch Level 12
Compiler Version:
Version not available.
Startrfc Version: 2018-08-15

Thanks for your quick response.
I have solved this issue by installing Visual C++ Redistributable Packages for Visual Studio 2013
