--- Comment #23 from Vincent Povirk madewokherd@gmail.com --- This bug should be fixed in Wine Mono 4.6.2. Current Git Wine (https://wiki.winehq.org/Git_Wine_Tutorial) or 1.9.8 when it's released will download and install this version.
Or, you can download it at https://dl.winehq.org/wine/wine-mono/4.6.2/wine-mono-4.6.2.msi and install it in Wine 1.9.7 by running "wine64 msiexec /i wine-mono-4.6.2.msi".
