In ‘Other’, you will want to check the boxes next to ‘Script mods allowed’ and ‘Enable custom content and mods’. Select the Options menu from the in-game menu, then click on ‘Game options’ and ‘Other’ in the left-hand toolbar. You need to enable mods before you can use them! This can be done from The Sims 4 Launch menu. You can see your mods in-game by left-clicking on your selected sim, which will then showcase any mods and mod options applicable. You can disable this pop-up, but it might be useful when it comes to double-checking that your mods work and will show up in the game. There should be a pop-up when you load the game up, which will showcase all of the mods and custom content you currently have running on your game. Restart The Sims 4 so that your new mods are launched along with the game. Drag all of your extracted files from this mod into your mod folder.
Navigate to your documents folder in a new window, click on ‘Electronic Arts’, then ‘The Sims 4’, then ‘Mods’, which should showcase a folder with all of your mods in it.
