Re: CC won't allow The Sims to open!

Hi @tommidani You could check that it's not related to your Anti Virus, or similar.. some experience that problem. Especially if you've not played in a long while. 

However, the mods or cc would be bound to need updates since you've last played, as is the norm after any patch (the last being the 21st Jan).

You can fast-track this procedure a bit by deleting known broken mods/cc and get the updates *more on that in the spoiler below.. 

I'd still recommend the 50/50 or cull method to find any broken mods, once checking your antivirus, getting newly updated mods, and if it still happens.

  1. Remove the mods from your folder to the desktop
  2. Delete your localthumbcache file found in your TS4 folder [Documents > Electronic Arts > The Sims 4]
  3. Repair game, by right clicking the cog near 'play'
  4. Run the game, to see if it runs ok, now without any mods/cc
  5. note: use a vanilla / new game for this process, don't run your old one
  6. Now, if all went well, try transferring one cc folder at a time.This helps narrow down which is broken.
  7. Trying the game each time, you do the process.. to see if it loads your game without issue 
  8. Before starting your game each time, also delete the localthumbcache file  from the sims 4 folder.

With each new patch, many mods are updated and will require checking up on them all..  More tips at my post here, here on maintaining your game, including more instructions on the 50/50 method.

Spoiler
  • Apart from culling your folders one by one, or the  50/50 method, to narrow down the broken cc or mod, that is all you can do, (restarting and checking your game each time) you'll simply need to find the broken mod/cc it and remove it
  • Mods & cc are well known to cause various in-game issues please check for updates to them / where you found them; do this also > after any sims update or adding a game pack,


  • I also use Sims 4 Studio for batch fixes, as it solves a lot of problems in bulk (but not all.) It's also available for Mac. And is updated frequently, with pack relevant bug fixes.

let me know how you go
