Open the Dr.Web application; click on Menu 
→ License → Enter a new serial number. Enter your serial number and click on Activate.
No additional actions, including reinstallation, are required. This same method can be used to activate a serial number for a purchase/renewal of Dr.Web Security Space that comes with a free mobile version.
Activation error
If any error messages appear, try to activate your license using a different network connection.
