Function Start-SleepProgress
        Pause script execution for specified time and show a countdown timer with progress bar and message.
        Sleep for a specified amout of time. Show a progress bar with a countdown timer and message.
        The countdown timer formats the time so that it is easy to tell time remaining
        using the largest time values that makes sense for the amount of time remaining.
    .PARAMETER SleepHash
        The length of time that script should be paused passed as a hash value.
        Time can be specified in any combination of seconds, minutes, or hours.
            $SleepTime = @{"Seconds"=10}
            $SleepTime = @{"Minutes"=10}
            $SleepTime = @{"Hours"=10}
            $SleepTime = @{"Hours"=1; "Minutes"=10; "Seconds"=30}
    .PARAMETER Message
        The message you wish to display on the progress message.
        Default message is: Please wait for script execution to continue...
        $SleepTime = @{"Minutes" = 10}
        Start-SleepProgress $SleepTime
        $SleepTime = @{"Hours"=1; "Minutes"=10; "Seconds"=30}

The progress bar and countdown do not show up on the screen. Show-InstallationWelcome dialogs show up before and after. It seems to process, but does not show anything. Is Write-Progress only for inside of a powershell command window?

Yes, it is only for inside a powershell command window. This is more for sys admin type script people write.
