Защо файлът се презаписва, когато KeyPath е зададен в Wix

Всеки път, когато инсталирам нова версия, тя презаписва съществуващия файл accounts-example.ini.

Поведението при презаписване се очаква за accounts-example.ini, но ще имам друг файл user.db, който не иска да бъде презаписан.

Пише, че ако KeyPath е настроен на „да“, тогава той не презаписва съществуващия файл, нали? Как мога да конфигурирам Wix да презаписва един файл и да не презаписва друг?
