Sorry, but it seemed to me to be pretty clear that when he said "If he can download the installer, and is only having problems with the online-installation process, it meant that I had to be using the online installer (and it would stop, fail or encounter some other kind of error), hence not relevant in my case.
And yes, of course the firewall would be an issue if I was using the the online installer / doing an online-installation as the helper file would need to initiate one or more outgoing connections (which would either be blocked or approved by whatever firewall I was using) to download the file(s)/data needed to complete the install.
Regardless of what was written, I see how the wget would be of use though as you guys need to know which load balancer is serving me the wrong file. What I don't understand is why your setup can't just serve the offline package which is requested through the download.comodo.com subdomain or the particular URL http :// download .comodo .com / icedragon / update* / icedragonsetup.exe (whichever you are using at the time).
* Forum link has this as extra
Surely any request to that specific URL would get served only one particular file. Not rocket science. Seems your redirects are screwed up.
If I have the time I will do the wget for you next time round if it so happens that I get to the forums before your redirects fix themselves.
