Serial number/Authentication key

During installation of NVC5 you will be asked for a serial number (authentication key).

If you have purchased a version of the program you have received / will receive a permanent key to use.
 This key is valid for the product(s) and length of time regulated in your license agreement.

If you want to update an existing version of Norman Virus Control, you will receive a permanent authentication
key from your Norman subsidiary or distributor.

By using the key DEMO you will be allowed to install the program. However, updates, including new virus
detection files requires a valid authentication key.

Norman strongly recommends that you download and read the documentation before you start using NVC5.
Documentation in several languages is available from this page.
