• If you are using Dr.Web on a subscription basis — you do not need license key files or registration serial numbers. The required identifier (ID) is already imbedded in the code of the application installed on your workstation. You can find it in your Subscriber account area on your service supplier’s website. If you use Dr.Web via the SCC (you bought a subscription on Doctor Web's site), the subscription ID is located in the My subscriptions section.

If, after trying all relevant methods, you failed to restore your serial number, contact our technical support service. Attach to your request documents confirming that you are the rightful owner of the license as per these rules.

Doctor Web does this to protect the rights of legitimate license owners. Sometimes licenses get stolen — for example, when a computer is getting repaired at a service center. Some users publish their serial numbers on the Internet or give them to their friends, thus violating the terms of the license agreement and making it possible for anyone to apply for a renewal discount. To protect the rights of the rightful license owner, part of the serial number is hidden in Dr.Web services. The entire serial number is only visible to the license owner:

• in the email received from the Dr.Web eStore
• on the license certificate.

Never show these documents to anyone if you do not want to lose the privileges enjoyed by rightful license owners.

You can verify this in the License Manager (enter only the serial number, and do not fill in the email address field).

If the license is active, you can get full information about it in the License Manager (the list of software products and protection components for each product, the validity period, whether the license includes technical support services, and other useful information).

• If you remember the wrong email address you used for registration, change the registration email on your own by using this service.
• If you do not remember this address:

If that happened:

• contact the store where you registered your license, and try to find out what email address was used; or

You are probably trying to renew a Dr.Web Security Space (Dr.Web Anti-virus) license, and purchased a Dr.Web box containing two serial numbers (or two licenses, each for one PC). When you were registering the first serial number from the box, you specified your old license’s serial number. As a result, you ended up with a new license whose term had 150 days added to it as a renewal bonus. Most likely, you tried to register the second serial number from the box and again specified the serial number from your old license. Since 150 days were already added to the term of your new license, Error 401 occurred when you tried to register the second serial number. Register the second serial number as a new license to which the renewal bonus does not apply.

Under the usage terms for a trial, you can only get a trial once a year. This error occurs if a user attempts to get another trial before an entire year has passed since their previous trial license expired.

• If you previously requested a three-month trial, renew your trial license at a 40% discount and keep your system protected for another year. To do this, in the Renewal Wizard enter the serial number of your trial license.
• If you opted for a one-month trial, Doctor Web recommends that you purchase a new license..

This error occurs if a trial key file is transferred from one computer to another. This violates the usage terms of the trial.

• If you need Dr.Web to protect a different computer, request a trial for that computer.
• If you have already used your right to one trial per year per computer, and you wish to keep your system protected, purchase a Dr.Web license.

Register the serial number via our website. To add a key file to the anti-virus, follow the instructions found in the registration email you received.

IMPORTANT! To register Dr.Web serial numbers, always use an email address whose mailbox is accessible only to you. Doctor Web will be sending a key file with instructions on how to use it, and service messages about the status of your licenses to this address. You will need to use this address in order to contact our technical support service, get a renewal discount, and use the many other services available on our website.
