Downloading Cmake through Powershell script - powershell

Question

I am trying to write a Powershell script for downloading the cmake zip file and installing it on a computer. While I thought it would be a simple task I am running into some issues with connecting to the cmake website. Here is my code:
$url = "https://cmake.org/files/v3.13/cmake-3.13.0-rc1-win64-x64.zip"
$output = "E:\test.zip"
$client = new-object System.Net.WebClient
$client.DownloadFile($url,$output)
When I run it, I get an error:
System.Management.Automation.MethodInvocationException: Exception calling "DownloadFile" with "2" argument(s): "The underlying connection was closed: An unexpected error occurred on a send." ---> System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send. ---> System.IO.IOException: Authentication failed because the remote party has closed the transport stream.

It looks like there is something with the cmake website that is closing the transport stream and preventing me from downloading the file. What should I do? How can I get around this?

Try adding the following lines preceding your code:
# Avoid errors with Invoke-WebRequest:
[Net.ServicePointManager]::SecurityProtocol = [Net.ServicePointManager]::SecurityProtocol -bor [Net.SecurityProtocolType]::Tls12
