Re: The Sims 4 will NOT launch/open

@CreepyVibes101  This is exactly what happens when an antivirus blocks Sims 4 from opening, although there are of course other possible causes.  It may or may not be enough to simply set exceptions for TS4_x64.exe and Origin.exe—some antivirus programs have additional settings that can be a problem.  For example, if you use Avast, AVG, or Sophos, please see this guide:

If adjusting your antivirus settings doesn't help, please let me know which one you use.  Please also run a dxdiag and attach it to a post.
