Re: Error - TS4_x64.exe

@beboppeanut  I'd still like to know what antivirus you use, because some of them have additional relevant settings, and "disabling" them doesn't always mean disabling every feature that might interfere.

Additionally, please clear Origin's cache:

and repair the game: open your Origin game library, right-click on the Sims 4 icon, and select Repair.

If that doesn't help, open [install path]\The Sims 4\Game\Bin and trash TS4_x64.exe, then repair a second time, which will force Origin to download another copy of the .exe.
