Windows x86_64 did drop support for 16-bit Windows applications. And a sad number old installers are 16-bit (even for 32-bit applications, as it meant they could give a user-friendly message on 16-bit Windows)—so much so that for some InstallShield and Acme installers they have a hack that reads the data files using a 32-bit copy of the installer application! See http://blogs.msdn.com/b/oldnewthing/archive/2013/10/31/10461992.aspx http://blogs.msdn.com/b/oldnewthing/archive/2013/10/31/10461... for some fun discussion about that BC hack. Makes me sad that I can't install Civilization 2, even though it's a 32-bit app.
