1. Try a new user account.
2. Google "How to manually uninstall Chrome."
And try installing it from Ninite.com
My Chrome stopped opening. Firefox and Edge work fine. I'm using Win 10 Home on a Lenovo laptop.
I looked in Task Manager to see if there was some piece of Chrome running that needed removing (Firefox sometimes does this). Nothing there. So I tried to uninstall and reinstall Chrome, but the uninstall failed. So I tried a plain re-install. Downloaded the install file and started it. It seemed to work but then it gagged and said there was an Error 3. I clicked on Troubleshoot and there was something about installing Sawbuck to track the install progress. I did that. Then I tried to install Chrome again. (I hope Sawbuck is automatic, because I didn't tell it to run before i tried another Chrome install).
Finally I got something. a "Where to now" page displayed in Chrome. In the tab behind that was Google, which is my home page. But the Where To? page wouldn't stop spinning, so I clicked Close Tab. All of Chrome went away. And won't come back, so I'm back where I started. Firefox and Edge work; Chrome doesn't. How do I fix it?
