I can't image what computer would not come packed with Arial... regardless, you can include the font file as an embedded resource and either load it into your application (I think you can only use it for GDI+ in this case, not for fonts on controls) or you can install it into Windows (I don't know the specifics of this). However, there is still the issue of licensing. If you are not licensed to distribute this font then it may be technically illegal for you to do so.
