SharePoint 2013 Installation

For the runing of the SharePoint Wizard the SQL advanced option "max degree of parallelism" must be set to 1. If this advanced option is not set before runing the wizard and the current Account does not have more than the standard rights (Security Admin, DB Creater),the setup fails.
