Chocolately `Get-ExecutionPolicy` - Uncaught ReferenceError: Get is not defined - shell

Question

I am following the Chocolately Install steps (Windows 7), but have run into a couple of problems.
Firstly, I've opened Command Prompt (opening it with Run as administrator), but when trying to execute Set-ExecutionPolicy Bypass -Scope Process -Force; [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1')), I get this error:
Uncaught SyntaxError: Unexpected identifier
..with the https: part of my command highlighted.
Further, when I try to execute Get-ExecutionPolicy, it results in:
Uncaught ReferenceError: Get is not defined
Any ideas what could be wrong?
* UPDATE *
When I try the same command in PowerShell, I get this error:
PS C:\Users\mylogin> Set-ExecutionPolicy Bypass -Scope Process -Force;
[System.Net.ServicePointManager]::SecurityProtoc ol =
[System.Net.ServicePointManager]::SecurityProtocol -bor 3072; iex

Answer 1

Download chocolatey latest version from Chocolatey.org
Rename file extension to .zip
Extract the file
Open PowerShell
Open elevated PowerShell calling:
Start-Process powershell -Verb runAs
Go to the tools folder in the location where you extracted Chocolatey
Call: & .\chocolateyInstall.ps1 to allow Chocolatey to install
Add a path to the choco location to system environment PATH:
C:\ProgramData\chocolatey\bin
Restart your consoles, and VS Code (if you use one)

Chocolatey.org requires TLS 1.2 to be able to connect. This error indicates that you don't have support for that installed:
System.Net.WebClient).DownloadString ('https://chocolatey.org/install.ps1')) Exception setting "SecurityProtocol": "Cannot convert value "3312" to type "System.Net.SecurityProtocolType" due to inv alid enumeration values. Specify one of the following enumeration values and try again. The possible enumeration values are "Ssl3, Tls"
The section from the blog post I linked to earlier should help:
If you find yourself provisioning machines such as Windows 7, Windows Server 2008, or older, you will find that those machines will not be able to communicate with the Chocolatey Community Repository after we implement this change. For those instances, you will need to use alternative installation methods for Chocolatey. We strongly recommend using the offline Chocolatey installation as it provides the most flexibility and reliability.
On the Chocolatey install page the requirements are listed:
Windows 7+ / Windows Server 2003+
PowerShell v2+ (minimum is v3 for install from this website due to TLS 1.2 requirement)
.NET Framework 4+ (the installation will attempt to install .NET 4.0 if you do not have it installed)(minimum is 4.5 for install from this website due to TLS 1.2 requirement)
My suggestion would be to fully patch your Windows 7 system, install .NET 4.5 and then try it. Remember Windows 7 has been out of support since January this year.
