Previous releases of calibre are available here.


calibre 2.x uses Qt 5 which is known to be incompatible with some Windows XP machines. If you are using Windows XP and calibre crashes soon after startup, use calibre 1.48, which works with all Windows XP machines, from here. Simply un-install calibre 2.x and install 1.48, doing so will not affect your books/settings.
