Need help downloading Half Life version


I downloaded the package several times but everytime I run any of them, I get an error:

My antivirus is not interfering (although it did the first time, but after the first download I disabled it and still nothing) so I am unable to install it. I do have a legit digital copy of Half Life on steam so it’s not that.


Where did you download it from? So I can give it a test to see. Because it does kind of look like the download is incomplete, but if you downloaded it several times that makes it a bit unlikely.
