Solution

The activation code may be needed for activating the application after installation, transferring it to a different device, or in case of license issues. For instructions on how to find the activation code, see this article.

If you cannot find the activation code, go to subscription details on My Kaspersky. Sign in to My Kaspersky. Go to the Subscriptions section.

• You removed the license and activated the application several times.

To reset the activation counter, submit a request to Kaspersky Customer Service by choosing the topic of your request. In your request, please provide the following information:

• If you purchased your license on the Kaspersky website, specify the email address you entered when completing the purchase.
• If you purchased your license in the online store of a different company, attach a screenshot or copy of the email sent to you with your activation code.
• If you purchased the application offline on a CD, attach a photograph of the card or brochure with the activation code printed on it.
• If you purchased the activation card, attach a photograph of the flip-side of the card with the activation code printed on it.

If you have auto-renewal enabled, you do not need to enter an activation code when the license expires. The license term is updated automatically after the purchase of the renewal.

It may take up to 24 hours between the payment and the update of the expiration date in the application window.

If the renewed subscription is used on multiple devices and its term failed to update on some of them, do the following:

1. Open the application and select your profile.
2. In the subscription section, click Details.
3. Click Update status.

If the renewed subscription is used on multiple devices and its term failed to update on some of them, do the following:

2. Click Update status. 

If refreshing the status did not help, try deleting the license and then activating the application once again with the same activation code. See this article for instructions.

Cause

The error "Activation code is invalid for this region" occurs if you attempt to activate the application with an activation code that was intended for use in another country or region. For example, you may have gotten this error if you bought or downloaded Kaspersky Total Security in your home country and then tried to activate it while abroad.

Solution

To avoid this error, activate the application in the country you purchased it in.

This error can also occur if you are using VPN while activating the application. For example, you have Secure Connection enabled in Kaspersky VPN Secure Connection. Disable Secure Connection and try to activate the application again.

If the issue persists, submit a request to Kaspersky Customer Service by choosing the topic of your request. In your request, provide the following information:

• Region where you tried to activate the application
• Activation time and date
• Activation code of 20 symbols (four groups of five characters)
• IP address of the computer on which the application is installed. To find out your IP address, you can use one of these services.
• Your Internet service provider and a screenshot of the main application window of the application you tried to activate. See this article for instructions.

Cause

There can be one of the following reasons:

• Your activation code applies to a different application.
• You are entering the code from the Kaspersky ONE application.
• You are entering the code issued in 2011 or earlier.

Solution

If you are entering the code from the Kaspersky ONE application or the code issued in 2011 or earlier, submit a request to Kaspersky customer service by choosing the topic of your request.

If your activation code applies to a different application:

1. Find the application that can be activated with your activation code. See this article for instructions.

   • Kaspersky Standard
   • Kaspersky Plus
   • Kaspersky Premium
   • Kaspersky Internet Security
   • Kaspersky Anti-Virus
   • Kaspersky Total Security
   • Kaspersky Small Office Security
3. Install the latest version of the application and activate it with the code.

1. Sign in to My Kaspersky. If you do not have an account, create it.
2. Go to Subscriptions.
3. Add your activation code to the corresponding field. If the activation code is added successfully, the page will display a new subscription.
4. Click on the subscription that you have added.

The page will display the subscription details in the following blocks:

• Top block with the application name: subscription or license status, subscription or license expiration date, activation code, number of devices that can be covered by the subscription.

• Apps: applications that can be used under your subscription or license.
• Users: information about the users with whom you have shared the subscription or license.
• Additional info: subscription or license activation date and expiration date, days until the subscription or license expires, license key.

It is impossible to extend the number of protected devices in the current license.

For example, if you bought a license for three devices, you can use it at your choice: for one, two or three devices. You cannot add a few more devices and accordingly recalculate the price in the license.

When the license expires, you can renew it and select the option with more devices.

It is impossible to reduce the number of protected devices in the current license.

For example, if you bought a license for three devices, you can use it at your choice: for one, two or three devices. You cannot reduce the number of devices and accordingly recalculate the price in the license.

After the license expires, you can buy a new one with fewer number of devices.

For Kaspersky Standard, Plus, Premium, see the instructions in Online Help.

For Kaspersky Internet Security, Kaspersky Internet Security for Mac, Kaspersky Anti-Virus, Kaspersky Total Security, and Kaspersky Small Office Security, you can enter an activation code in the Activation window.

Cause

• The website may contain phishing links, malicious code or other threats.
• When the website is accessed, content from the higher-level website may be loaded, which may be considered unsafe by Kaspersky Security Network.
• The site may contain content considered sensitive. If Parental Control is enabled, such website will be blocked.
• Issue with a website certificate. This may be a sign of a fake website, also the issue can be caused by an expired website certificate, or a website certificate based on a Windows root certificate that has expired.
  For example, on September 30, 2021 a DST Root CA X3 certificate has expired. To view the Windows root certificate on which the website is based, in the Kaspersky notification click View certificate and open the Certification path tab.

Solution
