Following on from this post:
I get the same error:
Error occured loading plug-in Details: Failed to load language 'IronPython 2.7.5': Method not found: 'Boolean Microsoft.Scripting.Utils.ReflectionUtils.IsInterface(System.Type)'.
I do have another version of IronPython installed but I need this to use numpy in the 32 bit Rhino 5. Uninstalling this is not really an option.
Does anyone have an alternative work around?
