Re: SimCity: Cities of tomorrow isn't launching on windows 10

I know it can be frustrating. I don't know about all of EA's games, but in this case, SimCity is an older game with no more development, so as the computers evolve, there are bound to be problems with it. I can successfully run it on Windows 10, so it's not like it's a lost cause or anything, but sometimes it can be a bit tricky for some people. I hope I can help to get you running. There are a lot of little things that can make a difference. Don't be too scared of the list, it looks long, but they're all quick little tweaks.

Always run installation files "As Administrator". 

1. Firewall and Antivirus - Make sure SimCity.exe and Origin.exe are added to exception lists. If you have BitDefender installed, disable it.
2. Graphics drivers and Windows OS are patched and updated to newest versions
3. SimCity.exe and Origin.exe - Set them to run "as administrator"
4. Nahimic 2 from MSI - this is an audio management program that comes with MSI motherboards. Disable or uninstall it. Nahimic 2 is known to cause this issue.
5. Copy Update Files to SimCity folder. Go to Program Files (x86)\Origin Games\SimCity\SimCityUserData\Patches\UpdatedApp  Select all files (Ctrl-A) and copy (Ctrl-C). Go to \Program Files (x86)\Origin Games\SimCity and paste (Ctrl-V). Choose to overwrite any files that already exist.
6. Disable Origin in-game In Origin main menu, right-click SimCity icon, Game Properties, check the box that says "Disable Origin In-game"
7. Run in Windows 7 or 8 compatibility mode - right-click SimCity shortcut; choose Properties > Compatibility tab > Check the box to run in Win 7 or 8 compatibility mode
8. Disable Proxy if you're using one. If you're not, try using one.
9. Monitor Settings - SimCity does not work with dual monitors, so set it to use one only. Also, no higher than 1080p resolution (no 4k)
10. No Mods -  if you have any installed, uninstall them

If none of these work, try a Clean Boot and attempt to launch SimCity. If it launches, you'll have some detective work to do. Enable one startup program at a time, reboot, try SimCity, until you find the program that is blocking it. Once you find the offending program, disable or uninstall it. You should be able to launch SimCity successfully without doing the clean boot after disabling the offending program.

Definitely post back and let us know whether something worked. If it still won't run, reply back with any error messages you're getting and attach a dxdiag report. How to Dxdiag
