I'm not sure I understand. As far as I can see the download of "Eikon API Proxy - Windows" under the link you specified only contains the readme file. So, I'm not sure what you tried to run and how you experienced the errors you mentioned. In any case if you use Eikon on Windows and you installed Eikon application, you don't need to install Eikon API Proxy, as it is embedded within Eikon application, as stated on the Downloads page you referenced. Please follow the Quick Start Guide to get going with Eikon Data APIs.

@gamma_long more information on what you are doing is needed. Where did you download the Eikon API from. RFA and Eikon API are completely different beasts. Python is the only supported language for Eikon API.

Thank you Gurpreet, I downloaded the Eikon API Proxy - Windows from here:

https://developers.refinitiv.com/eikon-apis/eikon-data-api/downloads

What is the error message when you download and install it. The proxy needs Eikon installed and running on the same machine, and isn't even needed with the latest version of Eikon on Windows.

See the Eikon python API quickstart and tutorials here.

Thank you Alex, I could install correctly.
