Does Sseutil Work Properly On Vista?

Does sseutil work properly on vista? I need a way to programmatically detach a user instance on Vista.
The following launches and runs ok on XP.
Doesn't run on Vista? Is there some problem with Process on Vista? sseutil runs ok from the command line in Vista.

public void DetachDatabase(string filePath)
{
ProcessStartInfo startInfo = new ProcessStartInfo("SSEUtil.exe");
startInfo.WindowStyle = ProcessWindowStyle.Normal; //.Hidden;
startInfo.Arguments = "-d "" + filePath + """;
Process detachProcess = Process.Start(startInfo);
while(!detachProcess.HasExited)
{
Thread.Sleep(1000);
}

}
