wbadmin command can't run from windows service

string path = "D:";
string wbadminPath = Environment.SystemDirectory + @"\wbadmin";
string wbadminEvent = "start systemstatebackup -backupTarget:" + path + " -quiet";

        try
        {
            int exitCode = 0;
            ProcessStartInfo start = new ProcessStartInfo(wbadminPath, wbadminEvent);
            using (Process proc = Process.Start(start))
            {
                proc.WaitForExit();
                exitCode = proc.ExitCode;                    
            }
        }

If I execute this code in Console Application, - It works. If I execute this code in Windows Service I have this error:

Command Line Interface for Microsoft BLB Backup has stopped working

Okay, so I know I'm to late to be of help, but hopefully someone else will benefit from this.

Windows Services cannot interact with anything with a GUI or that requires user interaction. Basically when you call Process.Start(start) it tries to open the CMD window which a service can't do. You can use something like:

            start.UseShellExecute = false;
            // Do not create the black window.
            start.CreateNoWindow = true;//This stops the GUI

HOWEVER it is worth noting I tried for hours to get this particular command to work and could not. I ended up scrapping the entire idea after hours of work and research. In general you can run CMD commands from a service using the .CreateNoWindow, however it does not seem to work in this case (it fails to find the WBADMIN process). If I find anythign new on this in the future I will update.

Here's a thread talking about why services can't access GUIs anymore
