Absolutely CANNOT Get the Sims 3 to launch from the launcher no matter what I do

alyssastanton12​  Your dxdiag doesn't list any Sims 3-related errors.  That could be because newer errors have crowded those out, or because the game is being blocked from starting, as an antivirus could do.

If you haven't tried to play in a while, the former is a distinct possibility.  So in that case, please try to launch the game, then look for new errors in the Reliability Monitor.  Click 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 open 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.

No error means the game is likely being blocked, so in that case, check your antivirus for any recent actions involving Sims 3, and set exceptions/exclusions as necessary.

If you don't see an error and you can't find any evidence your antivirus is interfering, please create a new admin Windows account and try playing there.  Make it local, as in, don't link it to your Microsoft account or any email address.  You'll be able to (try to) play without reinstalling anything.
