Greg,
Welcome to the forum. 
You may first negotiate your options ā¦ 
ā¦ try running ā¦
powershell /?
ā¦ in a CMD or PowerShell console window to learn how to properly start the PowerShell and execute a script file from a command line.
Are you sure about that? ā¦ you may use the command line option -NoExit.
