Ошибка «Недостаточно памяти» на Win10 64-битной, но не 32-битной?[РЕШЕНО]

/ 17 июня 2019

Я использую код из сообщения Марка Бертеншоу: VB6 - используя POST & GET из URL и отображая в форме VB6

На 32-битной машине разработки код Марка работает нормально. Но на моей 64-битной машине это выдает ошибку нехватки памяти в коде: 

m_sOutput = StrConv(AsyncProp.Value, vbUnicode)

Возвращенные данные из http-запроса очень просты {"response": 2} или {"response": 6} и т. Д.

На 32-битной машине он загружает scrrun.dll из папки system32, но на 64-битной машине он загружается из папки sysWOW64 (в ссылках).

Это является причиной проблемы, так как я думаю, что сообщение об ошибке памяти - красная сельдь?

Просто не могу найти причину проблемы.
