Have seen may posts relates to same topic where one talks about the incompatibility of windows and runtime version and another one turning off Output Publisher in Designer Studio. But none of them works and thought of posing it back.
In my case I was being using an older runtime and till recently and then decided to upgrade the version from 19.1.23 to 19.1.86 which I believe more suite with Windows 10.
After installing the latest Pega Robotics Studio, I just wanted to make some changes to one of our existing automation and re-compile the code to fit in to 19.1.86 and then start getting this error.
I am not sure why it happens on 19.1.86 version. So, appreciate any valuable inputs.
Currently I am using Windows 10 Enterprise - 20H2 OS build 19042.1110 and IE version Windows 10 20H2

@HemachandraI This is because of the Pega Native Foundation (PNF) and not specifically the version of Runtime (or Studio) you are using. Make sure your PNF version ends with the same values as your Windows 10 version. Here is a link to the PNF build notes page.
This is a separate install from Studio or Runtime (although they are bundled together when you download). Be sure to install the latest PNF if you upgrade Runtime or Studio.
