@Bhue The Sims 3 launcher uses Edge in IE mode whether you use Edge or not. So please clear that data and try to open the launcher again.
A Steam install uses TS3W.exe, so if you tried to launch the game through Steam, that's why that .exe crashed. It's a good idea to uninstall the Steam version and also remove the associated registry entries. They're here:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Electronic Arts\Sims(Steam)
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Sims(Steam)
Hit Windows key-R, enter "regedit" without quotes, and before doing anything else, export a copy of the registry (File > Export) in case you accidentally delete the wrong entry. You can restore this version of the registry by double-clicking the saved file. Then navigate to each location in turn and delete all entries inside the Sims(Steam) sections. Restart your computer when you're done, then try to run Sims 3.
If you still can't play, please please 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 launch Sims 3, specifically after you've done the steps I listed. 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.
