Game Won't Launch

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?

@simsgamer900  This lastcrash is from a modded game.  Please remove all mods and custom content, as in, move the Mods folder to the desktop, and try again to play.  Delete any lastcrash or lastexception files you have and if you get a new one with no mods or cc, feel free to upload it.

I have the same exact issue it's happened for two whole days now and I can not get the game to load beyond the loading screen I have attached the errors I receive it's worth noting I have cleaned up files and repaired over 10 times now.

So I did that and mine launched. I’m going to try doing the 50/50 from there and see what happens 

I don't know how it works, but it's amazing. I deleted all the Razor software and the Sims is working. This, of course, raises questions for developers... But thank you so much!
