--- Comment #8 from Vincent Povirk madewokherd@gmail.com --- The stub was added to Wine Mono 4.6.2. Please update Wine Mono and retest. You can do this by either: * Building Wine from Git (see https://wiki.winehq.org/Git_Wine_Tutorial) * Testing with Wine 1.9.8 when it's released * Downloading the MSI installer from https://dl.winehq.org/wine/wine-mono/4.6.2/wine-mono-4.6.2.msi and installing it in Wine 1.9.7 by running "wine64 msiexec /i wine-mono-4.6.2.msi"
