Adobe progress bars are the archetype of jankie, they  steadily rise to 25% then stop for 20 minuets, pile drive suddenly to 61% then stop for tea and biscuits and then crawl like a disabled tortoise to 99% before deciding something went wrong at and it has to redo all 4 steps... it's even worse now with thier 'must be connected at all times' during install because even after the files are on your machine, if your dc'd for even a second it refuses to continue and forces you to start from scratch.
