I cannot check this. Maybe a system with Visual Basic Scripting Edition 5.0 is enough. This should mean at least Windows XP Home Edition (maybe that a system (Windows 2000, for example) upgraded to Internet Explorer 5 or greater be enough), with default install. Apart from this, program output, being this using command prompt (system console) or file redirection, when running youaccess_unicode (the unicode version of the program) uses Unicode (UTF-16) character encoding, to try to maximize idiomatic compatibility. This does not represent any problem to read output using the command prompt (system console), MS Windows Notepad or popular text editors as Notepad++ (redirecting program output using >) at least in my Windows XP, but can propagate certain confusion.
