'PowerShell' is not recognized as an internal or external command

Question

I have just installed Chocolatey via PowerShell, I tried running PowerShell both as myself and as administrator, and if I try running choco or cinst I get the following error:

PS C:\> choco /?
'PowerShell' is not recognized as an internal or external command,
operable program or batch file.

What do I do? I have a feeling this is related to more than just Chocolatey...

Answer 1

This can happen if a program is not on your PATH. Open a PowerShell prompt and enter

[environment]::setEnvironmentVariable('PATH',
"$env:path;C:\Windows\System32\WindowsPowerShell\v1.0", 'm')

then restart PowerShell.

this is not working for me. The error persists even after trying multiple times with PS both as administrator and user. – Hygeia

Answer 2

I found this helpful.

• Write cmd in the start menu, right-click and run as administrator.
• Then in the cmd, paste in this to install choco

@powershell -NoProfile -ExecutionPolicy Bypass -Command "iex ((new-object net.webclient).DownloadString('https://chocolatey.org/install.ps1'))" && SET PATH=%PATH%;%ALLUSERSPROFILE%\chocolatey\bin

Put Chocolatey on the path.

Edit the system environmental variable. Go to

System Properties → Advanced → Environment Variables → System variables → PATH → Edit → New

Look for where Chocolatey is. In my case it was at C:\ProgramData\chocolatey. Enter that, don't forget to put "\" after Chocolatey. I.e., it should be: C:\ProgramData\chocolatey\
