You may customize the list of internal messages used by the executable. For example, you may create localized versions of these messages for different countries/locales.
Note that some messages are parameterized. For example, the message "Service install: %s" is displayed when a Win32 service executable is installed and contains one parameter, referenced by %s. When customizing these messages, please ensure that the parameters are retained, otherwise the messages may become unintelligible. You can also include newlines in messages using \n
Customization of messages are project-specific. If you need to reuse customized messages, the best way is to open a previous project containing the customized messages, and invoke File... Save Project As... to save the customized messages to another project file.
