i am having the same problem but my game is the supernatural one plus it says i need to upgrade my game when i just did it and when i am gdoing it again its really really slow

im having the same exact problem, and im seriously considering returning the whole thing.

@ddsalove: Are you on PC or MAC

                       Are you trying to start the game pressing play on Origin or on the Sims 3 Launcher?

@eldruyor: Before updating your game, please read this on what to do before patching, it's very important that you read it.

                     After carefully reading the notes on what to do before patching, use the Super Patch to update your game.

Hi,

Have you patched your game up to date (1.63)?

Have you only recently installed Supernatural and did you have problems before you installed it? Did the installation seem to work? Perhaps you have a corrupted download.

Do you have any mods or custom content (if so, remove them until your game is working again).

For general advice, information and tips on how to play TS3 on a Mac, read BluebellFlora's guide here:

In particular, try moving out the whole TS3 folder from Documents and onto your desktop, let the game generate a new one and then see if you can play. It is possible that there is some problem within your current setup.

I'm also having the same problem. I am trying to install the Sims 3 from the Starter Pack and that error keeps coming up on Origin

ps.  I'm trying to install on a PC
