That's not it. What the issue is really us that a lot of XP installs are installed on computers that are just too old to run Qt5. The processors don't have what's needed to run Qt5. So instead of having a support nightmare, Kovid decided to end support for XP with Calibre 2.x.

That's not to say that all XP installs cannot run Qt5, but too many of then cannot and that's the problem. If you have a system capable of running Windows 8.1, then you have a system capable of running Qt5.
