I had the same problem, finally I went to stardock.com and downloaded it there through http. I suspect stardock central uses some protocol which is prone to mistakes in large files (it could be ftp based). I am saying it, because I have the same problem when I use ftp services on very large files. This is repeatable on two computers through my router (desktop and laptop). Funny thing, if I connect through wifi, there is no such problem, only I have problem if I connect through physical wire. May be wifi has extra ways to correct errors.

Actually I've been downloading it though the https, tried using a manager as well, no luck

You can just keep downloading it until you get the un-corrupted version. Yeah, I know, it's not a "solution", but it'll get you the game.

Actually my only attempts so far has been though the http, (the download manager for some reason doesn't give me the option of downloading FE) given that it always marks the corruption error at 96% (when the file is extracting itself), I am starting to think the issue is with the file in the servers...

I am using DAP

I've tried DAP and Firefox, will try in explorer now, if nothing else seems to be working

What's the file size of the completed (corrupted) download? Should be 3,217,279,519 bytes for 0.992. 

If you still have a bad copy of the file, grab the download from http://www.winmd5.com/ and check the md5 of it to see if there was corruption in transfer vs something happening when the self-extractor wrapper is running (which then kicks off the .exe for the install). Should be 0db9c530a846752a71a0c636fe828764. 

Stardock Central is checking the md5 of every 100MB chunk as it downloads it, so that should be accounting anything in the download path. It's using straight up http.
