During the design of the program, we decided not to add a menu for changing the program language. Rather, different setup files are available. All setups are also designed for both languages. By creating a file in the installation directory, the language can be changed to English. This is an empty file called lang.us. This file must only exist, but does not require any content.
If you would like to use British currencies and European data format, create a lang.uk file instead of a lang.us file. Conversion to Swiss francs will be soon possible, then with a blank lang.ch file.
