Installing Sims 3 Seasons

Hi!

Im trying to install Sims 3 Seasons, which I downloaded from Games4theWorld on Pirate Bay Then I used "The Sims 3 Mac Installation Guide" to install on mac. 

I created the .dmg without problem, then I open the Installer, i put the serial code and select a destination and its fine, in the game validation theres no warning so I click Install and then there comes my problem, It said it couldn't be install because the The Sims 3 version installed isn't update and its no compatible with The Sims 3 Seasons. 

So I thought if I applied the Ultimate Fix to the base game it will work, but I still cant install the expansion.

What can I do now?

Hello,

What is the current version of your base game?

I don't know. It just said "The Sims 3" 
How can I know? 

Hello,

You are unable to install seasons because your version is outdated. Please folow these steps:

1) Download and apply the manual patch: https://games4theworld.forumotion.com/t3597-can-t-update-the-sims-3-to-v167-fix-manual-patch
2) Check that the bottom right of your launcher says Version: 1.67
3) Install Seasons.
