This is a mess. On 10th January i purchased avast 4 professional edition. I downloaded it and double clicked on it. The avast message box came up and i clicked continue. It looked like it was installing - took about 10 seconds and only got as far as VPS and said it had finished so i clicked finish. My computer didnt restart and it hasn’t been installed. I tried a few more times but still it would not install. So I thought i had better install the free version as a only have a few days left with the free editon. which i think i have as now as later on when i tried to install the professional edition download the avast home edition installs instead. I’ve tried entering the registration key i got for the professional edition in the home edition it won’t accept it.
I’m at a complete loss. Can anyone please advise me how i can install the professional edition?
