Hi everyone,

I’m experiencing an issue with butterfly v0.0.05 — I want to upgrade but I can’t find the installer (.exe) or (.gh) file for the new version of _**Butterfly (v0.0.2).**_

on GitHub page, there’s only a ZIP file of the source code, and I’m unsure how to use it.  
I also couldn’t find any mention of Butterfly in the latest Ladybug Tools installer — it includes Honeybee, Ladybug, and Dragonfly, but not Butterfly.

The only available version of Butterfly for Grasshopper seems to be the older one.

Does anyone have suggestions or guidance on how to install the new version?

Thanks in advance!

@minggangyin but these are still the components of v.0.0.05. Or is this just not updated in the Grasshopper components?

Which version of blueCFD or OpenFOAM is needed to run Butterfly on Windows 11?

In here it is mentioned that one “must” be running Win 7 or 10. Will it still run on Windows 11?

thank you @minggangyin for your respond, but all the userObjects here are for 6 year ago.  
can you be more specific where are the installation files for the last version you meant?

Please replace all butterfly user objects and python code in grasshopper folder.
