Re: Run Sims 3 without Origin

there is a way ! - if you are running the disc version.

delete origin ( ignore the message that if you do, you will not be able to re-install),delete the Sims 3 and  all expansion and stuff packs from your computer.

re-install the base game and run. you will be asked (demanded) to install origin - decline and let the EA downloader install the updates ( about half, three quarter of a  hour's worth ).

re install the expansion packs. ( check the final screen on each installation- UNTICK the option to download/install origin, if present- it might even say that if you don't, origin will not be able to upgrade your game - this is rubbish - EA has stopped support for the Sims 3  and will no longer be publishing patches or upgrades- pure blackmail !)

open C:/program files/ELECTRONIC ARTS/EADM and delete the 'download patches' program- this stops the computer downloading and installing the origin set-up program. 

run the game as usual but with either the base game or  last loaded expansion disc installed in the drive- your pre-saved games will still be there. and ignore the message that the game cannot connect to Origin- yipeeeee !.
