Google Chrome Installer Download Failure Error

Greetings!
I had shared my recent problem of software on a different forum but got no answers. So this time, I am posting this question here because here, I see people do reply to questions. So friends, I have attached below the image of the error which I am receiving when I installed Google Chrome update.
Installer download failed. Error code = 0x800421f4
This error appears again and again when I run the update of the browser. I thought that there might be problem with my computer. So I tried the same update on a friend's computer. But again, this error appeared. Now I am stuck here and can't further figure out why the update was not getting installed.
So please, if anyone knows how to install this update or knows any other solution to it, then please reply to this question.
