Upgrade CRM 2015 to CRM 2016 at localhost Server

I have installed Microsoft Dynamic CRM 2015 at my localhost, local server that is accessible to me.

I want to updagrade my CRM version from 2015 to CRM 2016.

I started doing so,

In Settings > Administration > Product Updates

after filling all necessay fields, and logging in. I have to face this error message again and again.

Is there any solution? thanks.
