"Cannot connect to My Kaspersky portal" error when installing a Kaspersky Lab product

2018 Jan 10 ID: 11103

In some cases, you may get the error message Cannot connect to My Kaspersky portal.

The Kaspersky Lab installer attempts to send the license information to My Kaspersky and fails due to network traffic restrictions.

To fix the problem, you need to disable restrictions for outbound network traffic on port 443:

Open Windows Firewall.
In the left frame of the Windows Firewall window, click the Advanced settings link.

In the left frame, click Outbound Rules.
In the list of outbound rules, find and double-click the rule BranchCache Hosted Cache Client (HTTP-Out) for TCPprotocol, port 443.

The Properties window will open. Make sure you are on the General tab of the rule's properties window.
Select the check box Enabled.
On the same tab, enable the option Allow the connection.
Click OK to save the changes.
