Your challenge is to have the Hapsburgs deposed after 1864, but with the Austrian/Austro-Hungarian Empire remaining intact, at least until 1900. It cannot hinge on an Austrian loss in the Seven Weeks War, though you can hasten, delay, or prevent that war, as long as you account for it. The POD can be anytime after 1780. 'Intact' is defined as not losing any considerable amount of core territory (Kingdom Hungary, Croatia, and Cislethenian Austria) as a direct result of the Hapsburgs being deposed.

EDIT: It doesn't need to remain an Empire either.
