First I ran the command Import-Module PowerShellPack.

Then I tried to create, and display, a label as in the video example; New-Label "Hello World" -FontSize 40 -Show

This resulted in the following error.

New-Object : Exception calling ".ctor" with "0" argument(s): "The calling thread must be STA, because many UI components require this."
At C:\Users\Rhys\Documents\WindowsPowerShell\Modules\WPK\GeneratedControls\PresentationFramework.ps1:30292 char:29

    + CategoryInfo          : InvalidOperation: (:) [New-Object], MethodInvocationException

OK, I seem to need to be running in STA mode. I Googled "Powershell STA mode" and discovered a Stackoverflow thread. After reading this I thought I’d try starting Powershell with the switch -STA.

OK, that seemed to work. Now lets try to create that label again. First load the PowerShellPack modules again since we’ve started a new session.

Import-Module PowerShellPack

Now try to create the label again.

New-Label "Hello World" -FontSize 40 -Show

OK, that’s that hurdle over. Now I can get on with exploring what this tool can do for me.
