Hi,
I have avast home on my system and upgraded to pro edition and went to install it and it wouldn’t install. I chose the"change" option when asked what I was trying to do vs update etc. It did not take the key and it still reads as home edition.
I am guessing I should uninstall the home edition before I try to install the pro edition?? Please any help. I just don’t want to screw anything up. I am not great with the technical on computers. Thanks
