--- Comment #20 from Antonio Russo aerusso@aerusso.net --- I cannot specifically comment on this. I had to reinstall that wine prefix years ago, and was unable to get it working with vanilla wine and just running the installer directly. I wound up using Lutris [1] out of frustration (and it did "just work").
The situation may have improved since that (but I have not checked).
