Blender produces an error on the windows when exporting:

Could you provide a link to the mesh in question? I'll try to repro.
I put it again as it is written in readme:
1) copy io_three to C:\Program Files\Blender Foundation\Blender\2.7X\scripts\addons
2) Activate the Import-Export addon under "User Preferences" > "Addons" and then use the regular Export menu within Blender, select Three.js (json).
3) To enable msgpack compression copy the msgpack to scripts/modules.
When I export with the same settings as you have again and get the same error.
Installed on a different machine windows 7 when you export the same error.
810 line
from io_three import exporter
if settings[constants.SCENE]:
exporter.export_scene(filepath, settings)
else:
exporter.export_geometry(filepath, settings)
return {'FINISHED'}
I do not understand such as exported with the same settings in the screenshot above that but got the same error
Very very weird. As that segments executes the export function, it's not deep enough in the call stack to give any useful info...
Are you able to export simple primitives? Just the default cube, or something like that?
Yes I tried all the same error.
I can provide remote access, if it is necessary to solve the problem.
