Powershell start-process with -wait while running as administrator

[justjeffindc]

I need to be able to start a process and have it wait for the process to complete. For example, if I run the below:

start-process notepad -wait
[System.Windows.Forms.MessageBox]::Show("Started running.")

Notepad opens, and after I close it the message box pops up. This is exactly what I want to see except that the process I actually need to run needs to run as administrator. So I run this instead:

start-process notepad -verb runAs -wait
[System.Windows.Forms.MessageBox]::Show("Started running.")

Now Notepad opens and the message displays immediately.

What am I doing wrong?

I am no PS aficionado but this page seems to imply you need to run powershell itself as admin first. See the example at the bottom:
