The Game won't launch

LiaKnow  Is the game currently trying to use Intel or Nvidia graphics?  If the game is running long enough to update DeviceConfig.log, the file will list the GPU about 30 lines down.  It's in Documents > Electronic Arts > The Sims 3, and you can check the modified date to see whether it matches the last time you tried to open the game.  You don't need to provide the file; just let me know whether its date is current and which GPU it lists.

Please also look for new errors in the Reliability Monitor.  Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day.  Today is on the right.

Look for an error that happened at exactly the time of your most recent attempt to play Sims 3.  If you find one, double-click it to see more details, then copy that info and paste it into a reply here.  If you don't see a new error, check back in an hour or so—the Reliability Monitor doesn't always update right away.

An access violation is by itself too generic of an error to be much help in troubleshooting.  Often the faulting module is informative, but when that's the game itself, all the error is saying is "this app crashed because it tried to access memory in a way that Windows does not permit," which can mean almost anything in practical terms.  The "reading address" is the memory address involved in the violation, but that would only be useful in a live debugging situation where the person troubleshooting could see what data was assigned to that address at that moment.
