I don't know what the error is, but I have a hunch that if you redirect stderr (RedirectStandardError = true) and read the stderr stream (like you do with stdout) it will tell you. Alternatively, while debugging leave CreateNoWindow = false and maybe you'll see the console message (especially if it is waiting for a keypress; otherwise it might disappear too quickly to notice).

Note that you might need to set up async readers on stdout/stderr if the process isn't terminating. You can do that either on extra threads, or via the OutputDataReceived / ErrorDataReceived events (you need to set EnableRaisingEvents to true also).

If that still doesn't work; you could try running with UseShellExecute=true. This means you won't be able to redirect IO, so you might have to use > / >> etc to pipe the output to a file (ideally in temp), then read the file.
