OK. However, the activation process requires an internet connection to activate when installing and I'm not about to turn off anti-virus protection while connected to the internet. I did that a few years ago and had to reformat all of my hard drives. The AV was only off for about a minute . . . literally.

What I don't understand is why there's no problem installing and activating ver 1.0 with hotfixes 1 and 2 without disabling anything. So why is it necessary to disable other software for ver 1.1? And the subsequent update(s)?

I may give it another shot with turning off the Windows defender but I really don't think my AV software is the issue. I've installed other developer addons with no problems at all.

I would find it difficult to believe I'm the only one experiencing this issue, but as I've said I'll give it one more try but won't compromise my system. Worst case is I use version 1.0.
