Windows 10 trying to uninstall trial get setup error

I installed the trial of AVG Internet Security. It tells me it has now expired. I try to uninstall so that I can reinstall the free version and i get the error:

Another installation already in progress.

How can that be since my PC has been shutoff for 5 days and i have not tried to uninstall before?

What do I have to do to get this resolved?

Thanks.
