  • The PC has a firewall installed that blocks the internet connection which is required for installation. 
  • Internet Explorer has incorrect proxy server settings entered.
  • Kaspersky Lab’s servers are temporarily unavailable due to maintenance.


  • If you have a firewall installed on your computer, make sure that it doesn’t block the application’s internet connection. For more details concerning Firewall see this guide.
  • Reset Internet Explorer settings. See the instructions on the Microsoft support website.
  • Try to install the application again later (e.g. in an hour).
