I’ve write a ghpy plug-in for architecture design. It’s tested well in my computer.  
But some user’s computer get this error while other user didn’t. They both have the same Rhino6 and GH version.  
I thought maybe some plug-in are conflict with mine. But after they remove the other plug-in, still get the same error and no plug-in shows in GH.

Why this happened?

Here’s the plugin below:  
[LiteTools\_V0.18.01.30 for Rhino6.zip](https://global.discourse-cdn.com/mcneel/uploads/default/original/3X/e/8/e82cc3c4b694e51fb9d6da6fe3622dd3f90fc8cb.zip) (163.7 KB)

Did they install an alternative version of IronPython?
