Butterfly 0.0.05 bluecfd io error

[fourggg]

I am really sorry for disturbing,but I have tested several vision of rhino in windows 7 including rhino 6.12/6.2/6.5/6.8.
Same mistake shows in the exact same line of runmanager_bluecfd.py and case.py listed above.
when it comes to rhino 6.12/6.2 which means that there’s no need to install microsoftvisualc++2017, the error goes"Unable to translate bytes [BE] at index 0 from specified code page to Unicode" which happened in a HB issue here.

Color zones and surfaces by EP results - Unable to translate bytes

Hi, I started using Honeybee not to long ago and decided to do the tutorials to get acquainted with the plugin. Evertyhing was going pretty until I got to the “color zones by EP result” part. This component keeps showing and error saying “Unable to translate bytes [E9] at index 0 from specified code page to Unicode” I tried the “Color Surfaces by EP result” component but got the exact same error. Honeybee and Ladybug are both up to date, and also checked many different discussions, but couldn’t…

When it comes to 6.5/6.8, the error is as same as the problems listed above. I am poor in Python but may be these messages can be of little help.

Is there a fix/solution for this? I’m coming back to this on a windows 7 machine, Rhino 6, and am getting the same error as I had before.
Things I have verified on workstation:
Running Rhino 6 as admin
Blue-CFD core terminal running as Admin (environment ready).
Able to read/write to butterfly folder, (tested with simple code below)

parent_dir = 'C:/Users/chanley/butterfly/'
directory = "SomeNewDirectory"
path = os.path.join(parent_dir, directory) 

try: 
    os.mkdir(path) 
except OSError as error: 
    print(error)   

All programs installed with default settings, (US english langauge, no other language packs being used, default directories, etc…)
Anyone have any suggestions?

[chanley]

is it possible that this could be related to a path issue? As in, if a user account is in a domain, sometimes the path might come back as C:\Users\chanley.DOMAIN\appdata\etc… VS C:\Users\chanley\appdata…?
Just a shot in the dark. I am also testing on a brand new windows 10 machine…but still no luck.

I am having exactly the same problem.

[Lincy]

hi, i just meet something similar. But not exact same.

And to solve this i found the link:WindowError win32 exception · Issue #382 · ladybug-tools/butterfly · GitHub
BUT this solution will affect creating case from geometries
