Hi,  
I have downloaded the Dynamo Sandbox 2.17.0 and launched it using DynamoSamdbox.exe.  
When I inserted below node a warning appeared at the top of node.

Please check the image -

Circle.ByCenterPointRadius operation failed  
Could not load file or assembly (directory path where sandbox is unzipped) LtbG.ProtoInterface.dll’ or one of it’s dependencies. The system cannot find the file specified.

Much appreciated.
