YOONIHUN If you use a third-party antivirus, please set exceptions in it for TS4_x64, TS4_DX9_x64, and TS4_Launcher_x64; or the entire Bin folder they're in. Set an exception for EADesktop.exe as well. Then repair the game again.
If that doesn't help, please provide a dxdiag. Hit Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop. From there, you can attach it to a reply using the camera (Insert Media) icon included with the other formatting buttons.
