When Activating Or Updating The Abbyy License, Error: "HTTP request failed: proxy authentication required" is obtained

How to resolve when activating or updating the Abbyy license, an Error: "HTTP request failed: proxy authentication required" is obtained?

The error message "HTTP request failed: proxy authentication required" obtained during activating or updating an Abbyy license via the Internet, indicates that

  • authentication is required to gain Internet access from the network location Or
  • the proxy is blocking the Licensing manager to contact the Activation server for online activation.

In such a scenario, where there is a proxy in place or the application is installed in a closed network, other methods of activation can be used such as:

  • activations by e-mail or
  • activations by e-mail from another computer.
