Issues while installing pega robotic studio

I want to install personal edition of PEGA robotic studio latest version. In Installation guide it asked to install PEGA robotic studio 19 before installing 22. When I am trying to install, the installation is struck at Visual Studio Update 3 popup.

@DharmaReddy If you are only using 22.1, then you do not need to install 19.1. Those directions (admittedly confusing) are referring to situations where you need to support 19.1 solutions and 22.1 solutions. To get Update 3, you must contact customer support. They can assist you. This update has been moved by Microsoft and therefore the installer can no longer acquire it from the web.
