Thanks. I thought I was hitting all the correct steps.
The only difference between Installer and Installer-Win is which platforms it can run on. Installer-Win can only run on Windows (as the name implies) whereas Installer can run on any system with Java e.g. Windows, Mac OS X, Linux, and Solaris. If you're running Windows, it doesn't matter which one you choose, as they both do exactly the same thing. If you're running another system, though, like Mac OS X or Linux, your only option is Installer. This is because these platforms cannot natively run .exe files.
OP doesn't show Installer-Win, as it indeed has an older screen cap.
