@crinrict, he is receving error because of used copy only. Disc version doen't need Origin to install it, but if you ahd used any patch then it will ask for Origin.
If game is asking for account somewhere then it means it is checking it through internet connection if provided. So if you haven't applied and crack to stop it then game will not allow you to play because code you are using is already registered with different account.
So ask for Email account also when you are purchasing used copy.
I asked Graham about that and he said that the newer Sims Base game (the Sims Refresh) comes already patched to 1.42 and does require in fact Origin.
I do have the disc myself and do not have Origin installed but I bought it in 2009. My game is fully patched.
So if the base game was bought around patch 1.42, you do indeed require Origin now. You still don't need a permanent internet connection. Just one to verify once like the download version.
