Installation:

Warning.

Because the mod makes very big changes to the game. please do the following.

In the sims folder delete the following folders:

cachestr.

onlinethumbnailcache.

And delete following files:

GameVersion.txt

localthumbcache.package

This is done so that the game reloads the mods correctly.

Repeat every time the game is updated or every time, I updated said mod. (This process also works for any mod)

***********************************************************

Installing my interface mods is very simple, you just need to drag the mod folder to The Sims 4 mods folder.

Remember that my interface mods include optional patches that you should remove if you don't have those mods, as they could cause errors in the game's textures.

Note:

When updating my mods, you should always perform a clean installation; never overwrite existing mods.

One more thing, most mods are just retextures for that mod, since for various reasons it is not possible to create a real and functional patch.

In other words, I have to re-upload the entire conflicting mod, but modified, to create a patch, and that's not right.

Simply having the patch installed and changing the load order of the conflicting mod is more than enough to make the mod work.

If you want to know which mod requires a special installation, you can check out my collection of help posts and tutorials for the game.

If you don't know how to do it or need visual aids, check the FAQ post where you'll find all the instructions and tips to solve your problem.
