Just to clarify, if you own the base game and EP/SPs on disc and have registered or can register them (you were their original owners), then you get the rights to the Origin digital versions at no extra charge. And again, Origin can manage disc installs. That's not what you want since you don't want an Origin controlled game and Patch 1.69 in the first place, but repurchasing the games would not be necessary. That would be true for Steam, though.
