Everything fine now with this updated release. I installed it as an upgrade (after changing the Temp files drive) and the install and KillSwitch went w/o a problem.
Registered perfectly with the Win Security Centre and running well - Many thanks
waiting for this to be the rtm so i can grab the offline installer soon and upgrade my computer from 7 to 10 1909 so i can test it for further upgrades on my others computers…
