--- Comment #26 from Zebediah Figura  ---
I tried to retest this since it seems likely that it was fixed upstream by
01e072bb68. Unfortunately it seems that some workarounds have been omitted in
the description of this bug. I first need to install native .NET 4.6, otherwise
the program won't even install. Even then, though, I can't get it to actually
run, with wine 6.19; it crashes with the following exception:

Unhandled Exception: System.TypeInitializationException: The type initializer
for 'System.Windows.Application' threw an exception. --->
System.TypeInitializationException: The type initializer for
'System.Windows.Navigation.BaseUriHelper' threw an exception. --->
System.NullReferenceException: Object reference not set to an instance of an
object.
   at System.Windows.Navigation.BaseUriHelper..cctor()
   --- End of inner exception stack trace ---
   at System.Windows.Application.ApplicationInit()
   at System.Windows.Application..cctor()
   --- End of inner exception stack trace ---
   at NETFramework.PreloadWPF()

Is there something else that needs to be done, or has there been a regression?
