Upgrading Coldfusion from 10 to 2016 the installer doesn't recognize a previous version

I was following the coldfusion upgrade guide here and it says that during the install it recognizes the previous version and you have the option to upgrade or install side by side. I did not get that prompt and it installed side by side. Can I just uninstall the 2016 version? How do I get the 2016 installer to recognize the previous version?
