I just download the engine exe files as is and unzip it and upload into Arena, I make no changes. Once loaded I just add the Perfect book to the engine and make sure that tablebases are not active. I do the same with all engines. I don't do manual changes other than core and hash and ponder. This is why I cannot understand once installed why the name comes up. When you start of course it shows Whittington under the search and execution but why the Eugeny name in the setup section? I have only seen this twice ever, with Stockfish and Marco instead of Todd and now with CSTal 2.
