PC SDK DLL reference error

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.
