@VikasM46 I suspect that you will need a later build of the Pega Native Foundation (at the very least). It is likely that because your Windows build is likely current, but your Pega version is from over a year and a half ago that there are updates to Pega Robotics you'll need to have in order for it to work properly.
@VikasM46 What is the build version of Windows you are using?
Here are the build notes for the native foundation. You'll get the latest version available at the time with Runtime, so I would certainly suggest you upgrade to the latest version of Runtime/Studio. You can update PNF independently however. You would likely just get the latest one and you can download the latest Runtime version as that will have PNC inside the ZIP.
@VikasM46 You request versions from the link below. You must be a licensed user within your organization. Whoever your admin is within your organization can add you or open an INC with support to get you access.
