Hello,  
I would like to test an application with the PC SDK tool  
I have installed RobotWare 6.08 and PC SDK 6.08.

I have included the reference to “ABB.Robotics.Controllers.PC.dll” but at startup I have a compiler error as;  
“The type or namespace name ‘ABB’ could not be found (are you missing a using directive or an assembly reference)”

Maybe i need some license

My actual situation is as follow

## ---- Installed Licenses ---- License: 2XYZ-_ **-** __-_\_\_\_\_\_-\_\_\_\_\_\_V Product: RobotStudio 5.x Expires: 14/01/2019 06:41:28 Level: Commercial State: Expired Features: Execute, NX\_Converter, SolidEdge\_Converter, CATIA\_V4\_Conv"SolidWorks\_Converter, Inventor\_Converter, Parasolid\_Converter

thanks for any reply

Hello,  
No needs to have license to compil, as I know.  
Which version of RobotStudio do you have?  
What is the line your compiler fails?

When I clone a project from a remote repository which is using PC SDK references I get a reference error even if I have PC SDK installed.

The solution is to remove them from the references in the project, and simply add them anew.
