Sims 4 - Unable to start Initialization error at startup

I have tried everything in this thread, and a few things on my own, and am completely stuck.

I had been able to play it, and even have 35ish hours into it.  Never a bit of trouble before.

Now, no matter how I try, I can't get past the abrupt error that spawns when I try to run it.

At this point the only thing I can think of on my own is reinstalling Windows, and I DO NOT want to do this, when it is no garuntee it will help, and is a royal bag of worms to do just to try.

There has got to be a way to fix it.

What can I do to get more help?  I have submitted an Origin Error Report.  Report ID is: 072496167000ed52

I am having the exact same problem, only I refuse to uninstall my bloody Windows! How about we fix this, hmm, EA?

Worked for me 🙂 tnx saba_azh

So, since this worked for me, I figured I'd give a shot and post what I did. I did not reinstall origin or Sims 4 since I originally installed them, just an FYI. I also did not reboot my computer.

WARNING! - This instructional guide will cause your computer to look graphically messed up during launch, such as your desktop looking like a computer from the 1980's and basically all jacked up while the game launches. This is only temporary while the game launches and your computer will revert back to original settings when you exit the game.

1) Closed Origin completely ( This means logout and exit completely from Origin )

2) Right clicked Sims 4 Icon on my desktop

3) Selected Properties

4) Clicked on Compatibility Tab

5) Selected the Run as Admin check box ( Yes, this means turn it on )

6) I did NOT change Compatibility Mode ( I am running Windows 7 by the way )

7) I than decided to troubleshoot the remaining 5 settings all at once ( By this, I mean I checked ( Turned On ) all the Settings aka Run in 256 colors, Run in 640x480 and so on )

8) Launched Sims 4

9) Logged into Origin

10) Sims 4 Launched Successfully

Sorry that I don't know which one fixed it because after I got Sims 4 to launch, I tried to single out which one the settings I changed fixed it, but after turning all the settings back to default ( Turned Off ) I was still able to launch Sims 4. I don't know what happened or what fixed my issue, but all I know is, Sims 4 now works.

Don't try to reinstall your windows

I have the exact same problem, 47hrs of game played, yet i can't open the game anymore

i've tried reinstalling the windows and it didn't work.

i don't know what else to do

This is just so much more horseshit.

Why, with every launch of every game for the last 3 years have we had to deal with this?  I'm paying a premium price for these games.  I shouldn't have to do 3 hours of troubleshooting then 2 more hours of reinstallation after forking over $70.

Just so much more horseshit...

These steps won't help. I've got Origin and Sims uninstalled, removed all files/folders, run ccleaner, reinstalled both. Still same message. And both are on C:.

Got Windows 8.1, 64 bits.

I suggest to check if your Firewall is blocked the ActivationUI.exe, that's what I've got. Just allow the program through firewall, don't disable firewall then.

Same goes for Dragon Age (and probably all new EA games) too by the way.

That the problem that I'm having right now. I played for 47hrs and now it won't startup. 

Add Me to this list

I have had the game play with my mods uninstalled. I get the error when I put my CC back in. I have also been able to play the game 1 time with my CC

EA FIX THIS GAME!!!!!
