Error: 'Element 'Views' is not valid for content model: '
If you see following error message when starting presentation services, possible reason for error would be, you may have same tags twice or so.
In my case I have 2 time 'Views' tag in the instance config file. When I'm trying to start presentation services it has thrown following error. Just delete one of 'Views' tag then everything worked fine.
