Nothing would let me repair my game.

skiesnann  This error is typically related to an overly active antivirus.  So please set an exception in yours for EADesktop.exe.  If this helps, set exceptions for TS4_x64, TS4_DX9_64, and TS4_Launcher_x64, or the entire Bin folder they're in.

If setting the first exception doesn't help, disable your antivirus, temporarily of course, and repair, then test the game once.  As long as you don't do anything else at the same time, your computer should be safe, and you can reenable the AV and set the above exceptions when you're done testing.
