Norton360 was the first problem (note: I have Win-7’s built-in defender firewall disabled never run two AV’s on any machine). And yep, I had several issues with the install, but with help from several posts / threads, I got them all resolved in very short order. Too bad most of today’s users don’t have those learned skills. My first machine was a Kapro-64, back when Bill Gates was in 8th grade. Folks: I’m still new to RC flying and this RF9.5 Sim, but not to flight Sims or computers.
