It is confusing that Start11 Install is at the top, above the other "Open" apps which are grouped at the top, and not with the other uninstalled apps. It is the first one that I see. Now that I understand that it is not the one I need to open, which is further down the list, I won't worry about accidentally installing the older version on top of the new one.
It would be nice if there was a warning that you are installing a lower version during the installation process, in case one accidentally clicks Install of the v1.47 version. It would save the hassle of having to uninstall the old one to be able to re-install v2 again.
