@leocg I did and that didn't work. But here's something. Win10 has some sort of compatibility tester. So it tried to run it in Win8 mode. Then it tried XP compatibility mode. And that seemed to work. I'm up and running.

@sgunhouse Exact order of events after I download installer: Double-click on setup; screen pops up that says 'Accept and Install' and click on that; Get message from OS "Do you want to allow this app to install?: Click yes; Get message saying 'Extracting' and then 'Installing' with progress bar; looks like it's installing then get message 'Opera failed to install.' You now know everything I know.

@sgunhouse Exactly the same as in the screen above. "Opera failed to install. Failed to download Opera." Not sure if this'll be worth if for me. I was just trying to see what it was like as a browser but don't really have a lot of time to play with different versions, troubleshoot.

@sgunhouse Sorry, wrong picture.

I downloaded it but same result. I tried turning off the firewall, same result. Attaching picture just to show you that I have both installers.

Greetings. I thought I would give Opera a try. I have a Lenovo Yoga laptop running Win10. Nothing unusual and I'm running other browsers. But it fails to install. I've attached a picture showing the two versions I've tried. Nada. Puzzled.
