Well, this depends on your language, for example, the default path for the notepad is C:/Program files/Lionhead Studios/Black & White 2/tools/notepad.txt, im brazilian so Progam files for me is "Arquivos de progamas", when the installer tried to open the txt, it can't find it. You know what i mean?
And other thing, if you have more questions, please do not create more topics, post on the ones you've already created.
