Question: How can I remove an included UCI engine so that it is no longer displayed in the loading dialog of the user interface?
Answer: Delete the chess engine with the file extension*.exe from the directory where it was saved. The next step is to remove the corresponding configuration file. The configuration files for the UCI engines have the extension *.uci.
The location/default directory is normally
C:\Programs (x86)\CommonFiles\ChessBase\Engines.Uci
