Hi @anto.ac
Ah - glad you were able to get the .dll copied. You are correct that it would not work without that. Do you know what the problem there was? Was it just a ‘permissions’ issue? I’m sure some other folks have fun into similar issues, it would be great to know what the solution was if you don’t mind sharing?
For the other error, gotcha: that is an issue with older version I think. You can see the fix for that here:
Which version of Rhino are you using by the way? Regardless, hopefully if you download the latest version and follow the steps in that post it should work for you I hope. Let me know if you have any difficulty with it though?
best,
