The commandline argument of CreateProcess has a limit of 32768 characters (See http://msdn.microsoft.com/en-us/library/windows/desktop/ms682425(v=vs.85).aspx) on Windows NT and later. This argument contains all arguments passed by the calling program, in most cases including the program name itself. If you hit this limit you get a different kind of error, as there is nothing that requires this to be a path. If you get a long path error in the calling process the problem is a path directly passed to the CreateProcess API... The parsing of the commandline to separate arguments is part of the called process on Windows, so that would have been reported as an error of the process... not an error starting the process. (The parsing in the application is also the reason why different processes have different argument escaping rules...) Bert
