Good day. Reinstalled the system from scratch with reformatting the hard drive. The activation key was entered during installation. After installation, I entered the activation key again. Successful activation with the key from the first email. In previous downloads, I downloaded Yandex.Browser before activation, maybe it's about it. Thank you for your cooperation and sorry for the trouble. Sincerely, I will still use the services of Soft Computers.
