When I search for Draw Helix in the PluginStore and in the ExtensionStore (3.0), I only get one result: John McClenahan: SU Draw Parametric Shapes v2.5.3.
This doesn't seem to be Draw Helix.
The SCF Plugin Store and Extension Warehouse are not the only resources for plugins and extensions.
As for your success after turning the helix on end, Upright Extruder was intended to deal with the twists that occur around climbing paths as typically happens with Follow Me. It was shown in the tutorial.
