Game Won't Launch

ranart  Then you're not looking in the correct location.  Please use the link I provided earlier to find your user folder.

I did that but my game didn’t create a new mods folder. 

ranart  Have you confirmed that mods and custom content are enabled in-game; and that your mods are in the Sims 4 folder the game is currently reading?  Here's how to find it:

If that doesn't help, remove the Mods folder, start the game to create a new one, and move one mod to the new folder, but nothing else.  Let me know whether it works.

My mods folder is still intact for the new sims 4 folder with all my custom content inside. But when I launch none of it is there. What do I do?

thank you so much helped me a lot, I couldn't find anything to help me but this was my problem. you made my day

@1Lorna  You'll need to launch the game once in order to create the folder.  If that's not the issue, here's where to look for the folder:

I can't find a MODS folder, and have seemingly tried everything else!

Thank you. I’ll try that today. 

@IndigoAnjel  No, you don't have to keep playing like this, but you do need to test the content from your old folder that you want to keep.  Start with mods and custom content, if you have any, and you can use the 50/50 method if you have a lot of files to sort through:

Once you've done that, you can transfer the contents of saves and Tray (saved households and builds), UserSettings.ini if you care about event rewards, plus Screenshots and Recorded Videos if you care about those.  The game will regenerate the rest as necessary.

I came across this post because of this problem and moving the folder helped. But now what? Do I have to keep playing like this?
