IronPython stopped loading in 32bit

Rhino Rhino for Windows
1

Hi,

My IronPython plug-in is not loading anymore at the moment
in my Rhino 32bit. In the 64bit there is no problem at all.

Does anyone have any idea what could have happened? It looks like
the folder structure for the plugin is fine and hasn’t changed. Might something
external did change?

The error I’m receiving says:

Failed to load language ‘IronPython 2.7.4’: Method not found: ‘System.Collections.Generic.IEnumerable`1<!!0> Microsoft.Scripting.Utils.ReflectionUtils.GetCustomAttributes(System.Reflection.Assembly, Boolean)’.Unknown command: EditPythonScript

Thanks a lot, any help is greatly appreciated,
Jeroen

@piac mentioned to me that he had seen this in the past when people installed things like IronPython tools for Visual Studio.

Yes, I think it was either the IronPython Visual Studio tools or another IronPython installation on the machine.
