Licensed until 15 october 2017 but not managed to install the update!

Hello Birgitta,
Thank you for contacting us with your concerns and we regret to hear about the issues you are experiencing to install your paid version of AVG. From the information you provided, it is clear that you are using a free version of AVG Multidevice program. The program you paid for is AVG Internet Security (1 computer). This is the reason you are receiving the incompatible message when you tried to install AVG Internet Security.
Please uninstall AVG Multidevice program as described in this article http://support.avg.com/SupportArticleView?urlname=Uninstall-AVG-Zen
After you successfully uninstalled AVG Zen, please install your AVG Internet Security as per the steps in this article http://avgclick.me/InstallAV .
Please, feel free to let us know if you require any further assistance. Thank you.

When I did not succede to install using the licence number code supplied in the mail in October I uninstalled the licenced AVG and since using the AVG Free to stay protected! Now when trying again I get message: "You already have another AVG product on your computer that is incompatible with the one you are trying to install. For more information contact Customer Support for help". As those trials have taken a lot of my energy I need precise help for free to uninstall and install the "Renewal AVG Internet Security 1 computer (1 year) ". Alternatively to stay on AVG Free. Please help me. /Birgitta
