Would you like a hand to get Chrome back up and running?

What is happening when you try to download it, do you have a screen shot or error of the point at which it fails?

Have you removed all the previous versions of chrome before reinstalling?

I had a bug with a Win10 update in recently, my chrome was freezing on loading up, it refused to auto update. I found just reinstalling chrome worked. Just one of those random things that happens, probably different to your issue but a fresh install should work.
