  • A firewall application installed on your computer blocks the internet access for the application installer. 
  • Incorrect proxy server settings are specified in the Internet Explorer settings.
  • Kaspersky Lab servers are temporarily unavailable due to maintenance.



  • If you have a firewall installed, make sure it does not block the internet access for the application installer. For more information about firewall, see this article.
  • Reset the Internet Explorer settings. For instructions, see the Microsoft support site.
  • Try to install the application once again in an hour.
