You can import your Symantec Network Access Control 12.1 license into a Symantec Network Access Control-enabled management server only.

You can start the License Activation Wizard in the following ways:

  • The Symantec Endpoint Protection Welcome screen that appears after you install the product.

  • From the Common Tasks menu on the Home page.

  • The Admin page of the Symantec Endpoint Protection Manager console.

If you activate or import your license from the Welcome screen or the Common Tasks menu, you can skip the first three of the following steps.

    I have a serial number

    You may receive a license serial number when you or your Symantec Partner purchased the license. If you have a license serial number, select this option.

    If you are an eFlex (Symantec Enterprise Options) customer and have an eFlex-generated serial number, select I have a Symantec License File.

    I have a Symantec License File (.slf)

    In most cases, a Symantec license file (.slf file) is sent to you in an email from Symantec shortly after you complete the purchase process. The file arrives attached to the notification email as a .zip file. If you have received a .slf file, select this option.


    You must extract the .slf file from the .zip file before you can use it to activate your product license.


    The .slf file contains the information that is unique to your license. To avoid corrupting the license file, do not alter its contents. You may copy the file for your records.

    You can find information about eFlex at the following URL:
