Which default messages?
For the messages during installation, look into the file
Applibs\distkit\langage.ini where are stored the strings used by the
installer. Take a backup copy and modify for your own purposes.
I have never tried that but it should work as expected. Usual disclaimer.
If you want to translate application default menus, use custom menus or
install the Run-Time Engine for your language on the target machine.
