Sims 3 won't launch

As the game is brand new and unplayed surely it has the factory settings!

This is for resetting the user files but yes, if you were never even able to play the game, that most likely won't help.

Maybe adding the sims3launcherw.exe file to DEP will help (don't know though): https://help.ea.com/article/dep-settings-for-sims-3-on-vista-and-windows-7

If that doesn't help either, last resort would be reinstalling the game:

Try uninstalling following the instructions here: http://simswiki.info/wiki.php?title=Game_Help:TS3_Uninstall

Make sure everything Sims is gone from your computer, then reinstall. 

All this time I haven't mentioned I got the game on Origin! Does this make any differene?

I don't think so, did you try suggestions above ?

Tried all of the above to no avail!

Then I don't know. Sorry I can't help.
