Just a quick note to myself: when Gimp-win-remote won’t work, adding “gimp-2.2.exe” (with the double quotes, although I suppose it would work without them, too) between the “gimp-win-remote.exe” and “%1” in the gimp-win-remote.exe\shell\open\command registry key does the trick. Picked this up from gimpwin-users.
Good Noodles.
