Thanks guys for replies.
Hi Eddy, there is a automatic process after the purchase (I think it is all, credit card details, payment etc is done within the GUI and not through the web browser) I remember it took quite long before the program upgraded to Internet Security. It took quite a while towards the last part on the renewing and activation. So there was no prompt on entering license key. The strangest thing but it just worked that the program name showed Internet Security with the new GUI. The free version that was used a year ago and used to do the upgrade, the version is different and the GUI is different. I cannot simulate the process anymore.
Yes David, I did the resending of the license file to the registered email. And received the license key. In the email, it says to double click the license file to install, but I have not tried yet. Because I was doing for someone else, and need to confirm what's her screen looks like now in Avast, and whether or not it is still showing 'left something in the cart" error.
Thanks again.
Daryl
