You use the activation workflow to activate a new license, to renew an expiring license, and to convert a trial license to a paid license.

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

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

    If you activate your license from the Welcome screen, you can skip the first three of the following steps.

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


The main console screen is slightly different for the Small Business Edition than that shown here. However, the Licensing Activation Wizard is identical in both versions of the product.

    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 customer and have an EFLEX generated serial number, please 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.


    Warning: 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.

  6. Do one of the following tasks based on the selection you made in the previous step:

    • If you selected I have a serial number, enter the serial number, and then click Next.

    • If you selected I have a Symantec License File (.slf), click Add File, browse to and select the .SLF file you extracted from the .ZIP file that was attached to your Symantec notification email, click Open, and then click Next.

    The Technical Contact is the person who is responsible for maintaining and managing your Symantec Endpoint Protection system. You must fill in the information for Primary Contact even if it is the same as the Technical Contact. The last action on this panel is to acknowledge that you have read the disclosure statement. Upon making the acknowledgment, the Submit button becomes available.

    The wizard displays a message that the license is activated.
