My AVG Ultimate expired, renewed for 2 years, have new registration code. Every time I attempted to install, I receive "Installation Error" Previous version installed, remove and try again.  I have uninstalled all AVG on my laptop, but there must be some code hiding somewhere as I continue to get error message. II have been trying for a week, and have been patiently waiting to AVG tech support to respond,…nothing so far, so I am here seeking knowledge. Thank you !!
