Installation Check ListConfigure Platform Server settings with the Configuration Tool

  
Hello,
I am trying to complete the Installation Checklist in order to Configure Platform Server settings with the Configuration Tool, Platform Database, but I am getting an error stating "Failed to grant Admin permissions to user 'sa' on catalog 'Outsystems'".
the user sa has been set has the owner of the DB and and provided all the credentials available.
The checklist configuration I am using is First Install + (Deployment Controller Servers + Front-end Servers + Database) + Standalone + 

Microsoft Windows Server 2008 R2 (64 bit editions) + 

SQL Server Authentication with username and password in connection strings.
Thank you for helping,
Mike
