if you've contacted Avast?
I cant complete the upgrade to the paid for home version. The instructions specifically say to launch the downloaded file but NOT the licence file which is to be done later. But as i had the free version on my system it prompted me to uninstall that and then reboot which it seemed to do automatically.... all very confusing. So now when I now launch the Home (paid for) version the wizard asks for a licence number or an activation key but where the hell do I find these or have I just wasted ?44 on this software.
I am not a techie and so just want the damn thing to work.
I am very frustrated by this process and wonder if I have made a big mistake buying the product having only got my PC back from the repair for a virus.
Thanks
