Internet Security still wants a license after installing Ultimate

Hello Janice. Thank you for contacting us. Yes, you should have removed the old AVG Internet security before installing AVG Ultimate. Please uninstall AVG 2015 from your control panel and re install it by clicking on the "Protection" component in your AVG Zen. And if you would like to preserve the settings of your AVG program, replacing C:\ProgramData\AVG2015\DB</a> and C:\ProgramData\AVG2015\Cfg</a> folders after re installation will preserve settings. Thank you.

OK, will do.  Please help your other current customers and revise the install program to identify that a previous product exists and tell them at installation time to unstall the existing product.

I had received a notice that my AVG Internet Security for 5 computers will expire soon.  So yesterday, I purchased, installed and configured AVG Ultimate successfully on 3 devices. It seemed that everything installed correctly.  Today, I'm once again receiving a notice that AVG will expire soon and wants a renewed license.  Should I have uninstalled the old product before installing Ultimate?  What should I do at this point?  And if I do need to uninstall/reinstall something, how do I keep all my settings / configuration in the process?

OK, will do.  Please help your other current customers and revise the install program to identify that a previous product exists and tell them at installation time to unstall the existing product.
