Repeated full screen reminders to renew when I am only half way through

Hello Alan.
We're sorry to hear about the inconvenience caused. Could you please let us know which version of Windows OS are you running on your PC? Thank you.

I had AVG free for many years and updated to full protection on 5.3.15 for one year. I took out a two year tune up on 4 May 2015.
I keep getting told my renewed antivirus is ready to install but when I click it it states cannot be done as already in progress error Oxe001f921.  It comes up every few minutes and when I look at data I am told my free ware is expired. What can I do?
