Let me know the information required when activating Arcserve UDP v6.5.
As a specification of Arcserve UDP v6.5 product, you do not have to activate as long as the license is registered properly.
Therefore, the information (Fulfillment Number, etc) required for the activation is unnecessary. Even if you are asked the information, there is no problem going forward with leaving it blank.
