Do you mean the Windows 'start' menu and the Windows 'control panel'? If so, I think you have both versions installed but you can uninstall the number 12.x.
When I wanted to upgrade to number 14, I first unistalled number 12 (maps are not deleted by the uninstaller) and then I installed number 14, checking 'early map access' as I had read here and it worked soon. Number 12 doesn't appear anywhere anymore...
My post refers only to the Setup Utility, not to the navigation program. With that program I have just version 14.
But for the setup utility I have 12 in the start menu and in the windows control panel and as name of the utility and for the directory but on the utility window itselfs it shows me "14.1.2 FREE" in the corner ...
yes, my above answer referred to the setup utility.
Before upgrading to v.14, I first uninstalled both the setup utility v.12 and the navigation program. Then I installed the setup utility v.14 and the navigation program v.14. If you installed v.14 without uninstalling v.12, well, maybe it's still working fine, but there can be something messed up in your windows registry.
