How to install expantions,if i have the original base game?

Hello everyone,
i have installed the original basic game, sims 3 and late night..i downloaded from this site some expansions(seasons,pets and town life stuff)how to install these expansions?please helpme.thank you:)

follow this step by step guide https://games4theworld.forumotion.com/t1171-must-read-how-to-install-the-sims-3-correctly

thank you for your answer.i will tell you what happened exactly.I downloaded sims 3 from origin-ea games because i have installed it again before one a year ago.i updated it to 1.47.i played with it,with no problem.Yesterday,before your answer i installed seasons.i used seasons's update 1.42.but it didn't work because 1.42 is older version than 1.47.Then,i wanted to use the seasons's crack but the bin(sims 3) is empty.appeared a message which told me to insert original seasons cd.so,your instructions are ok about me?

To place the crack when using an origin downloaded game, you're going to look for "C:\Program Files (x86)\Origin Games\The Sims 3\Game\Bin" instead of Electronic Arts.

It's ok.You are right.Thank you.So,i am going to follow these steps,but i am going to place the crack to the Bin(as you say)or i am going to place the crack only,will be ok?

Hello,

Just re-do step 3 and 4: https://games4theworld.forumotion.com/t1171-must-read-how-to-install-the-sims-3-correctly

But copy the crack to this folder instead of the folder that's described in step 4: C:\Program Files (x86)\Origin Games\The Sims 3\Game\Bin

Good luck and please let us know the result!

Thank you very much:)When i try it,i will inform you.

Hello,
