--- Comment #5 from shevvek.twitch@gmail.com --- My thought was, since in that link it looks like sometimes that error shows up with mono but not with .Net, maybe it would go away with dotnet in winetricks. Every time I try to install any dotnet more recent than 3.0, though, wine appears to crash, so I haven't been able to test it.
