Fix Chocolatey "Access is Denied"

Question

I just installed Chocolatey for the first time using this command in an admin cmd:

@"%SystemRoot%\System32\WindowsPowerShell\v1.0\powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "iex ((New-Object System.Net.WebClient).DownloadString('https://chocolatey.org/install.ps1'))" && SET "PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin"

Admin cmd output:

Getting latest version of the Chocolatey package for download.
Getting Chocolatey from https://chocolatey.org/api/v2/package/chocolatey/0.10.13.
Extracting C:\Users\CurrentUser\AppData\Local\Temp\chocolatey\chocInstall\chocolatey.zip to C:\Users\CurrentUser\AppData\Local\Temp\chocolatey\chocInstall...

We are setting up the Chocolatey package repository.
The packages themselves go to 'C:\ProgramData\chocolatey\lib'

A shim file for the command line goes to 'C:\ProgramData\chocolatey\bin'
  and points to an executable in 'C:\ProgramData\chocolatey\lib\yourPackageName'.

Creating Chocolatey folders if they do not already exist.

  'Batch file could not be found' is also safe to ignore.
  'The system cannot find the file specified' - also safe.

Ensuring chocolatey commands are on the path
Ensuring chocolatey.nupkg is in the lib folder

After restarting my cmd I still can't access choco commands:

There does not seem to be documentation on why this happens. How can this be fixed?

Answer 1

run your command prompt as administration then run command "choco install nodejs"

Answer 2

This is related probably to antivirus, in my case was Sophos and needed to add choco as a whitelist
