Hi
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.
Remember to always run installation files "As Administrator", and set Origin.exe and SimCity.exe to run "As Administrator". Once the files are copied, try to launch the game again.
Happy Building!
