AVG installation problem

Dear all,
I can install AVG 8.g anti virus free edition but the definition update will not execute beacuse, I think, I have a AVG Free edition for windows already that will not un-install.
I have tried to see if there is a repair option in the new AVG 8.5 but there isn't, only a custom installation option, which is not recommended for non-experts like me.
Despite trawling the internet, am stuck - what should I do?
Thanks
Sam

In addition, I get the following when re-installing the older version (done to try and repair and then uninstall)
Local machine: installed successfully
Installation:
