I was able to download and install Neon 1.0.2531.0 on my Windows 10 Machine. Now, when I try to run it or reinstall it, it closes immediately.

Sometimes I can see the box where it requests to become my default browser; sometimes it does not. In any case, it is not there long enough for me to react to it. I tried changing my antivirus program; no help.

All those ad process that terminate and stay resident create processes in Opera. I currently have processes that are subframes from google, squareup, openx.net, doubleclick.net, demdex.net, rfihub.com, googlesyndication.com, and doubleverify.com. I often see others, like facebook.com, rubiconproject.com, addthis.com. You can terminate those processes in Opera without losing much functionality, but you might get logged out of your GMail.
