Dragonfly Runtime error

I’m new to HB + LB tools . I’ve installed dragonfly recently trying to use some components but i keep getting this error . And i have no clue what to do . Gh file works on other pcs . I’ve reinstalled it and used LB Versioner but it didn’t work out.

If you’re trying to do Urban Heat Island modeling with the UWG, you should use the latest LBT 1.4 plugin instead of those legacy Dragonfly components.

After you install LBT 1.4, this dragonfly example that comes with the Food4Rhino download will show you how to run the UWG.
