The installation account must be a member of the local server Administrators group and have the db_owner role for the SharePoint configuration database.
To automatically activate site collection features during installation (optional), use an account that is also a SharePoint site collection administrator.
If the installation account is not a Site Collection Administrator for all site collections in a web application, then you should choose to not automatically activate the solution during the installation. Site Collection Administrators can activate the solution when they are ready to use it in their site collection.
