I'm new to installing this on the website but I have no instructions on how to place this in my sims 4 folder, please help..

I found a link with pdf tutorial but its explaining how to create your own traits, I don't want to create my own traits the ones I downloaded not working in CAS and that's what I want ...

do I jus install the mods into my mods folder?

First off, please don't triple post. Especially within a 40 minute timespan.

Secondly, "The Sims 4 Mod Constructor is a program for creating custom traits and aspirations in The Sims 4." and it sounds like you're having trouble with the traits themselves, not Mod Constructor. It's a modders tool, it won't do anything for your game. What traits are you trying to install specifically? Cats and Dogs patch broke a lot of things, is it possible that your traits just haven't been updated?

Yes I think majority of my cc traits isn't updated because neither of them is showing on cas when I create a family

Conserning the broken traits that was broken this November after the C&D patch, I think Sims VIP has a tutorial on how to fix them manually. I my self has fixed a number of those I have in my game that way.
I also downloaded Zebus mod Constructor, but as far as I could see it does not contain an easy batch fix for the broken traits. So the only solution is to go through them manually.
