Sims 3 lucky palms installation problem

np 🙂  that's what i thought your world may have been  🙂 ok if the world installed it'll be in the main menu +new game to select the world to play in you will still play from whatevergame you normally play from although Hidden Springs is the trickest one of them all to figure out from the guide 

for wolrds you redeem the code in your the sims 3 account once the code is redeemed there then download from your the sims 3 purchase history then installed once installed it'll be in the main menu +new game to select the world to play in you will still play from whatever game you normally play from also wolds will not appear in your origin my games tab

Guide to worlds scroll down a bit to see how to redeem the code in your the sims 3 account

Hidden Springs

The world can either be bought through Origin or as Code in a box in a retail store.

Hidden Springs is probably the most difficult to redeem if you bought the disc version (available also in the world bundle). The retail version does contain a disc but there's not much on it (the world sure isn't).  To make it even more confusing, when redeeming the code or going through the install process, for some the world isn't added to your purchase history but you get Simpoints credited to your account. You can then use to those to buy the world here: Hidden Springs. It doesn't matter that it says it costs 2000 SP on the page. If you got 2450 SP credited, that's what it will cost. The disc version is only for the world, there's no extra Simpoints. You can also only use those for the world itself and not buy something else.

There seem to be disc version around that give you a code that add the world directly to your purchase history. So if you don't get Simpoints, check there.

I'm unsure how the Origin version works but you might be getting points credited to your account as well.
