--- Comment #2 from Jim Henderson jim_henderson@sil.org --- Thanks, @Austin English, for your suggestion.
Ketarin is a 32-bit app, and I'm running it on 64-bit Linux.
Also, it needs DOTNET 4.5.2, so I had to do this command:
WINEARCH=win32 WINEPREFIX=~/.wine32 winetricks dotnet452
WINE-nube that I am, it took me quite a bit of research to work out that I needed to set those two variables in the environment of the "winetricks" command.
Thanks for getting me started in the right direction. I can use its editing function properly now :-)
