You cannot enable updating subscriptions after a publication is created.
To use updating subscriptions, you must also configure options in the New Subscription Wizard. For more information, see How to: Create an Updatable Subscription to a Transactional Publication (SQL Server Management Studio).
To enable updating subscriptions

On the Agent Security page, specify security settings for the Queue Reader Agent in addition to the Snapshot Agent and Log Reader Agent. For more information about the permissions required for the account under which the Queue Reader Agent runs, see Replication Agent Security Model.
The Queue Reader Agent is configured even if you use only immediate updating subscriptions.
