The information that BlackjackWidow mentioned is a great start especially this one:
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.
Few suggestions/questions for you:
- You say you don't get a game window but
- Do you see the game launcher show up or does nothing load onto screen?
- if you press CTRL+ALT+DELETE and go to Task Manager, do you see SimCity listed in the running programs?
- Do you get an error message?
- Right click on SimCity.exe and select Run as Administrator
- Delete "<origin_games_dir>\SimCity\SimCityUserData\WebStorage" folder and run the game as Administrator (that directory will get recreated so don't worry)
- Check your Antivirus software whether it is Defender, Avast etc and add SimCity to the safe list then run the game again
If those don't work, please find and attach to this thread the following files:
- In "<origin_games_dir>\SimCity\_Installer" find the InstallLog.txt and attach that
- In "<origin_games_dir>\SimCity\SimCity\SimCityUserData\Patches" find the UpdateLog.txt and attach that
Thanks
