Avg pc tuneup utility

i HAD DOWNLOADED AVG PC TUNE UP ON SUNDAY 4th JUNE 2017.
LATER I PAID THROUGH ONLINE YEARLY USAGE FEE. I GOTMY ACTIVATION KEY  O.K AND ACTIVATED THE UTILITY TO RUN.

hOWEVER AFTER TWO DAYS DUE TO SOME CLEANUPS NEEDED THE UTILITY WAS REMOVED FROM MY SYSTEM.
NOW I DOWNLOADED THE UTILITY AGAIN BUT DONT KNOW HOW TO USE MY ACTIVATION KEY (WHICH IS ONLY TWO DAYS OLD) SO THAT I DO NOT HAVE TO PAY AGAIN AND USE THE UTILITY FOR 1 ONE YEAR AS PER MY PAYMENT MADE ON SUNDAY 4th JUNE 2017.
