Have you checked that your computer is up to specification for Sims 3?
Hopefully, there is an easier solution than the only suggestion I have. I retired from computer programming more than 20 years ago, but, the message "unhandled exception" in my day indicated either insufficent memory or damage to upper memory.

I hope someone here can come up with something else, but, in the meantime, I would suggest checking your computer has sufficient memory.
Also, have you read the first sticky posted above
