ATTACHED ZIP. Where is offline installer?
Which further confirms the problem is your Antivirus, since it's an .html file that contains this:
"Website Blocked by Trend Micro Titanium"
So, your antivirus not only has mistakenly blocked a legit website, but has done it without even telling you since, I would expect a proper antivirus would clearly signal is doing something like that!
I suggest switching to a proper antivirus, or contact their support to report a False positive.
As I've said in one of my previous posts, the Offline installer linked in the Sticky thread of this forum, the one named "Offline installer".
