If I understand your problem correctly this has nothing to do with having a singleton implementation. You simply need to check if your executable is currently running.

You can do this by calling Process.GetProcesses() or Process.GetProcessesByName(NameOfExecutable) and checking the return values.

Alternatively use a Mutex as suggested above by others.
