avast pro edition not dowloading correctly

i have just purchased avast pro and although I received a key number, i have never been asked for it. What am I doing wrong here. I have downloaded it from the website but it does not go any further. Please help.

-= check your license via right click on avast icon on taskbar → About avast! → Check if you might have accidentally downloaded Home or you are using a trial version of PRO & check the entered license key too… If you want to insert a license key, just click on the license key button [it’s much better to copy-paste the license key than typing each one by one…]

Hello Chronoboi, I am doing a right clic on avast icon on task bar and cannot I seem to still be on my old avast that will expire in a few days. I looked for a way to delete it but have not found that button. Can you help?

You don’t have to delete anything, having selected about avast from the right click menu, you should see a pop-up window, see image, there is a button at the bottom of that window, ‘License Key…’ clicking that opens another window and just paste the key you were sent by email into that text box and click OK.
