Hello Katherine,
We apologize for the inconvenience caused to you.
I request you to use the remover tool from this link:http://www.avg.com/tools#tba2 and reinstall the AVG program that you are trying to install in your pc.
Thank you.
I had the free download for years. Then I upgraded to trail avg my mistake. The trial period ended and I tried to download avg zen and keep getting an error code 0xc007643
