Re: Windows XP 32 bit, Gallery?

@PastelQueen8 Please, download The Sims 4 Legacy - open The Sims 4 game details page, then select the Extra content tab and scroll down. Legacy Edition should be there for you to add it to your Game Library and download it.

The Gallery is indeed disabled in The Sims 4 Legacy Edition. Another option would be, if it's possible for you, updating your Windows to a 64-bit version.
