I like the idea of a popup message, but that one's awfully long, and telling users to delete their existing wineprefix is not necessary, and potentially harmful, if they don't read carefully enough. IMO, it would be better to refer users to the FAQ for actual instructions on how to create a 32 bit wineprefix.
