Here's a fish function to actually install the themes relying on win2xcurtheme:

function installInf -a installer scale
  if test -z "$installer"
    err "missing installer (.inf) path"
    exit 1
  else if test -z "$scale"
    info "default scale is 2"
    set scale 2
  end

  set themeName $(echo $installer | cut -d / -f1)
  set themePath "$HOME/.local/share/icons/$themeName/cursors"

  mkdir -p "$themePath" || exit

  set args "$installer" --scale "$scale" -o "$themePath"

  if command -q win2xcurtheme
    win2xcurtheme $args
  else
    nix run nixpkgs#win2xcurtheme -- $args
  end || exit

  info "successfully installed cursor theme \"$themeName\""
  info "at \"$themePath\""
end

usage is eg installInf "kuro/Kuro Cursor/Install.inf"
