Re: Cannot launch Sims4, System cannot find file specified

@imen19 ... You seem to be right...I can't verify because I uninstalled Avast along with any quarantined game files! Now I persistently get this launch failure now no matter what I do. So, before uninstalling and reinstalling my game again, I decided to let Steam verify my game files and sure enough it found 1 file missing (the ts4.exe file?). So,now I have my missing file back I can get the Sims to launch again. Thanks for this information, it seems to be the fix for Avast users.
