I just upgraded to Windows 10, latest build. All appears well but for installing either v8 or 9 beta of Smart Security. The install will begin normally, but after not long hangs and will not complete. I've used the uninstall tool and that works as expected, but every time I try to install the same problem results. Sadly, therefore, right now I'm stuck using *gasp* Windows Defender.
Has anyone else experienced this situation, and if so, come up with a remedy? Perhaps something or some service is running that is causing interference?
