With these parameters, launching of the new process still fails with 
same error code: 87
     with TProcess.Create(nil) do try
       ApplicationName := Config.PocketProgramName;
       Parameters.Clear;
       CommandLine := EmptyStr;
       Environment.Clear;
       Options := [poNewConsole];
       InheritHandles := False;
       try
         Execute;
       except
         got the exception error 87
       end

I've seen that FInheritHandles is forced to true in the first line of 
the Execute method whatever value is set in the property, while MS says 
it is not supported and shlould be false.
