Installing Software as a Non-Administrator Using Chocolatey

NonAdmin.cmd

:: Pick one of these two files (cmd or ps1)

:: Set directory for installation - Chocolatey does not lock 
:: down the directory if not the default
SET INSTALLDIR=c:\ProgramData\chocoportable
setx ChocolateyInstall %INSTALLDIR%

:: All install options - offline, proxy, etc at
:: https://chocolatey.org/install

CALL choco install puppet-agent.portable -y

:: pick an editor
::CALL choco install visualstudiocode.portable -y :: Not available yet
CALL choco install notepadplusplus.commandline -y
::CALL choco install nano -y

NonAdmin.ps1

# Pick one of these two files (cmd or ps1)

# Set directory for installation - Chocolatey does not lock 
# down the directory if not the default
$InstallDir='C:\ProgramData\chocoportable'
$env:ChocolateyInstall="$InstallDir"

# If your PowerShell Execution policy is restrictive, you may 
# not be able to get around that. Try setting your session to
# Bypass.
Set-ExecutionPolicy Bypass

# All install options - offline, proxy, etc at
# https://chocolatey.org/install
iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))
# PowerShell 3+?
#iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex

choco install puppet-agent.portable -y
choco install ruby.portable -y
choco install git.commandline -y

# pick an editor
#choco install visualstudiocode.portable -y # not yet available
choco install notepadplusplus.commandline -y
#choco install nano -y
#choco install vim-tux.portable

# What else can I install without admin rights?

For a quick non-admin installation I actually prefer this one-liner:
$env:chocolateyUseWindowsCompression='true' ; $env:ChocolateyInstall="$home\choco" ; iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex ; $env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine") + ";" + [System.Environment]::GetEnvironmentVariable("Path","User") ; choco --version

This code is confusing. Is it for installing Chocolatey itself, or is it for installing packages? If both, then why? Does one need to re-install Chocolatey on non-admin systems every time one wants to install a package? Or do most users only every run Chocolatey once, to install their favorite packages, and then never touch it again?

Also, the comment line "PowerShell 3+?" is confusing. Is it so common to still use PowerShell 2 (even though v.6 is current) that 3+ is commented out? Is there any advantage of using the 3+ command on modern systems? Why is it commented out?

Note: the official Chocolatey install documentation links to this gist.

$env:chocolateyUseWindowsCompression='true' ; $env:ChocolateyInstall="$home\choco" ; iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex ; $env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine") + ";" + [System.Environment]::GetEnvironmentVariable("Path","User") ; choco --version

This worked for me.
Thabk you very mcuh @pbb72

$env:chocolateyUseWindowsCompression='true' ; $env:ChocolateyInstall="$home\choco" ; iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex ; $env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine") + ";" + [System.Environment]::GetEnvironmentVariable("Path","User") ; choco --version

Thanks Bro.

check status for package (choco search: https://github.com/MrDKOz/HandyScripts/blob/12295ca13bf180612c2fb61c0710aaf8143eacfe/app-installer.ps1)

$env:chocolateyUseWindowsCompression='true' ; $env:ChocolateyInstall="$home\choco" ; iwr https://chocolatey.org/install.ps1 -UseBasicParsing | iex ; $env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine") + ";" + [System.Environment]::GetEnvironmentVariable("Path","User") ; choco --version

Finnaly, my brain doesn't have to hurt just to install chocolatey. thanks @P4z!
