The first thing you may wish to do is change the software language. In order to do this you go to edit > preferences... > general and chose the language you need from the drop down list in the top left corner and press "OK". If it is the first time you have chosen a language, BlueBrick will need to download the files from the internet. A new window for the Download Center will open. Press "Start Download" to download the language.
If this help file was translated in your language, next time you choose help > content and index , the help will be displayed in the language chosen for the application.
