WinZip activation codes have only one use. They are a way to provide registration information to you. As soon as your activation code has been used it is disabled. It will not work again.
Registration information for a single user license includes the Registered to name and the Registration code.
| Once an activation code has been used to generate registration information, it is disabled and will not work again. |
If you did use your activation code already, even if you are not aware that it was successful, and then you try to use it again at a later time or date, you will be advised by the WinZip Activation server that The activation code has already been used.

Rather than the activation code, you should enter your registration information. If you do not have your registration information recorded, please see this Knowledge Base article (What is my registration code?). At the top of this article there is a Quick Search feature where you can enter your email address. If your email address can be found by the server, a message containing your registration information will be sent automatically to that email address. If your email address cannot be found, you should then fill in the Detailed Search form beneath the Quick Search and submit that. Your form will be sent to Support and a service representative will use the information you supplied to search the registration database. A reply will be sent to you at the email address you supplied.
If you have any questions about this information please email Technical Support.
