Adobe Vulnerabilities Still Working?

Sorry for posting this here bu, however,t I couldn't ask you herehttps://null-byte.wonderhowto.com/how-to/hack-like-pro-hacking-windows-xp-through-windows-8-using-adobe-flash-player-0155228/.

I tried this on windows 8.1, followed the steps, but once I pressed enter in the Internet Explorer , the site didn't open and there wasn't any activity on my terminal. I tried a lot of different exploits later or earlier, but all of them were a disappointment. What am I doing wrong?
