downloading ASP.NET 5 runtime and tooling for offline installation

Hi,

How can I get the installation files this link:

https://go.microsoft.com/fwlink/?LinkId=627627

downloads and installs on VS2015?

This link is from the site Installing ASP.NET 5 On Windows:

https://docs.asp.net/en/latest/getting-started/installing-on-windows.html

with the title:

install the latest ASP.NET 5 runtime and tooling.

What I basicly want is to download the file once and keep it for future installations, without having to download everything from beginning.

Thanks

Kourosh
