"Simcity has stopped working" Before it even started.

Hey I have had the same problem, where  I wasnt able to play the game for the first 2 days i had it. After talking with EA customer service via Chat i went through many options to see what may have been causing the problem. At first the EA customer service agent had me open Program Files (x86) > Origin Games > Sim City and delete the "SimCityUserData" folder. This allowed me to play the game, but I had to go through the tutorial again. After shutting the game down after this, I ran into the same problem old error - "SimCity has stopped working" when I attempted to join another server. So I went and deleted the "SimCityUserData" folder again, and was able to successfully start the game, however I had to go through the tutorial again. So that was a temporary fix, but I think i encounted the "SimCity has stopped working" error a few more tries after doing this. 

Finally, the  customer service agent and I, tried another option. He had me right-click Origin and go to 'properties'. Then click the 'compatibility' tab. Here I un-checked the box saying "Run this program in compatibility mode for:". Previously, this box was checked, which seemed to be causing the problem. Anyways, this finally seemed to work, as I can now play the game without going through the tutorial each time. So I figured I will spread the message since I have endlessly been reading forums for a solution. Good luck.

Disabling origin-in-game in the advanced settings fixed the problem for me.

how can you disable origin in game?

I tried everything and it keeps coming up --'

I have windows 8 😕

To disable Origin in game, open the Origin application on your desktop. In the top, left corner click on the drop down box that says "Origin." Click on the option titled, Application Settings. Once you are there, you will click the sidebar option that says Origin In Game. Uncheck the box that says Enable Origin in Game.

Please do not dig up the graveyard.  This thread was decayed, just bones, and you disinterred it for no useful reason. 

This fixed the issue for me on my older laptop! Still not working on the newer one though! Thanks!!!! 🙂 

If you guys are still having trouble I found the solution, go to where SimCity is installed E.G D:\Origin Games\SimCity then go into SimCity, right-click SimCity.exe go to the compatibility tab then check the "Run this program as an administrator" box. works for me 100%

Worked perfectly for me, thank you!

If using Windows 10, likely an exception needs to be configured.  

Settings > Updates / Security > Windows Security > Virus & threat protection > Controlled folder access > Manage Controlled folder access, add an exception.

Controlled folder access protects files, folders, and *memory* areas on device from unauthorized changes by unfriendly applications.

Allow an app through Controlled folder access:

<file path>\SimCity.exe

Should work now.  This could apply to other older software too.

Otherwise, use Windows compatibility to add Admin and Windows 7 permissions also, but the security setting is the prime issue.
