Hi Team - I am installing Pega on my system, however I am getting an issue that the package can only be opened via Bootstrapper. I am following the installation guide provided in the training exercise. However, I am stuck in the very first step where the installer fails to open the package without a bootstrapper. Can some one help with this boot strapper or is it a sepearate installer to be installed as pre requisite if yes, can i get the link for downloading it please. (I have attached the error screenshot)
