Can't change Autolog Property

Question

Hy ! I implemented the tutorial about Windows Services written by Mahesh Chand from the section Tutorials. But there is a problem ! I can't find in the Property Autolog for my Win Service ( myService System.ServiceProccess.ServiceBase) and i can't access it from the code like : myService.Autolog ?? ). How can i change this Property to TRUE because i can't register the service using installutil.exe without this property !!
