Закачка из Интернета по протоколу https - возможно ли? - VB

Формулировка задачи:

У компонента MsInet есть свойство "протокол" и одно из значений HTTPS (при этом порт автоматически ставится верно - 443). Но данные не скачиваются. Попытка вызвать API-функцию URLDownloadToFile тоже не приводят к результату. На StackOverflow нашел подходящий диалог: пользователь приводит пример попытки загрузить через https (не работает). Эксперт ему отвечает и приводит URL с http.

Решение задачи: «Закачка из Интернета по протоколу https - возможно ли?»
