Need help reinstalling Killer Network Manager!!!

I recently reinstalled windows 10 home because there was a bug in the windows system file which I could not fix.

Now I've reinstalled windows 10 and redownload all my files and changed my HDD to a SSD.

But, I searched the web and I couldn't find Killer network manager anywhere and I've also asked the people in Alienware Service on Youtube, but they gave me a link which goes to a Dell Support with Alienware X51 with Killer Network Manager.

Then I noticed that their is no download link or a button.

In the time, I also disabled Adblock and Antimalware bytes...

Please respond as soon as possible
