Downloading Cmake through Powershell script

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.

   at System.Management.Automation.Interpreter.DynamicInstruction`4.Run(InterpretedFrame frame)
   at System.Management.Automation.Interpreter.EnterTryCatchFinallyInstruction.Run(InterpretedFrame frame)

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
