We just did a big refactor in the way that we identify the HVAC system template (in order to make it work with C# and the Revit/Rhino plugins we have planned). So this issue is likely caused by a mis-match between your components, which look updated to the latest version, and your core Python libraries, which seem to be of the old version on that machine. So just run the “LB Versioner” component again on that machine, restart Rhino, and your file should work.
