Sims 3 won't open after launcher

I did this and it did not work. Still will not launch. Mine is straight from Origin if that helps. I also did everything under the 'error still occurs' and it is still not opening.

What's your operating system ?

What did he do because I'm having the exact same problem

 I am also having issues with mine opening as well. 

I am currently using a Mac, OS X 10.9.5 and had recently gotten a new hard drive for it as the orignally hard drive had crashed. When I went to reinstall the game on the new drive, it would open the launcher & then crash. I uninstalled & reinstalled twice, both times ii get the "Unkown Error" message pop up, the launcher won't even open.

Any help would be greatly appreciated!

Honestly, he didn't do anything.  I clicked on the start button and it started.  Made me really mad too.

Hey I just Installed this game and all my packs and store stuff along with some exchange stuff and now my game won't even play after clicking play on the launcher now! I have a OS-X Yosemite 2015 version and have almost had it with this ordeal! I have the most recent patch I did what was instructed by many forums to use window mode when changing the graphic settings. I also did this even when changing sim settings and season settings. I feel cheated and appalled that I even invested in this! I have been a loyal EA customer since I was thirteen and now I feel completely disappointed! When I do click play on the launcher apple states that the launcher quit unexpectedly even though thats what it does. I have had to uninstall everything including the origin 5 times this month. Any help would be obliged. 

Thanks for the memories,
