Have you downloaded this yet? I did. It took me about 3 hours from start to finish because I didn't understand many of the security options. More than likely I chose too many, so later my grade program stopped, and I spent another 2 hours getting rid of it.
The program does not ask what security you have, and I thought since it was Microsoft, they could read it automatically. Therefore I added security without disabling what I had. Our internet provider sent me to the Router tech who said I probably had too many firewalls running at once, so nothing was working. It worked fine for a few hours, then began to stall, and I lost the internet connection.
He had me restore the computer, and all is well.
I just thought I would warn all of you.
