Add-Type: command not found

Question

I'm trying to create a basic GUI for PowerShell, but for some reason it can't recognize the Add-Type parameter. this is the code I've used:

# Init PowerShell Gui
Add-Type -AssemblyName System.Windows.Forms

# Create a new form
$LocalPrinterForm                    = New-Object system.Windows.Forms.Form

# Define the size, title and background color
$LocalPrinterForm.ClientSize         = '500,300'
$LocalPrinterForm.text               = "LazyAdmin - PowerShell GUI Example"
$LocalPrinterForm.BackColor          = "#ffffff"

# Display the form
[void]$LocalPrinterForm.ShowDialog()

when running it with: $ ./exampleScript.ps1

I get: ./exampleScript.ps1: line 2: Add-Type: command not found

what can be the problem here?

Answer 1

The add-type command is working fine with me I have version 5.1.18362.628

to find your PowerShell version type the following command:

$PSVersionTable
