Hi
Completely exit Origin & SimCity.
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.
Open Origin and then launch SimCity.
Always run installation & program files "As Administrator", and make sure that both Origin.exe and SimCity.exe are added to your antivirus exceptions lists.
