Not working on Windows 7 in Windows ISO Downloader Posted August 29, 2017 Thanks Carlos. I've compared your log with my server log, and there's a one-to-one correspondence of https calls. In the Fiddler log I can't see any error message with either microsoft.com or heidoc.net connections. This is no connection issue. Could you disable all plugins and anti tracking lists in your IE, and try again? If that fixes the issue, we can identify the culprit by re-enabling the plugins one after another.
