title: Continue installation even after download failure with Inno Download Plugin
body: <p>On some of the systems (mostly Windows 7), we are getting <code>Download failed: An error occurred in the secure channel support</code> error while downloading files using Inno Download Plugin. We tried adding <code>idpSetOption('AllowContinue', '1');</code> found from one of the answers but that did not solve the issue. The files we are downloading are not super critical, so we can ignore error if downloading fails and setup should continue.</p>
  <p><strong>Minimal, Reproducible Example</strong></p>
