Re: The sims won't repair

@sibuladpeenral It's most likely your antivirus quarantining the TS4_x64.exe file, this always triggers the legacy edition. Make sure you check your antivirus quarantine, give exceptions to Origin/EA app, TS4_x64.exe and maybe even the documents/electronic arts location, where your user data for the game is stored.

if a repair or a reinstall fails, you can also try to run Origin/EA app as administrator, but the antivirus exceptions should be a good start for that as well.
