@everlygreen There is no Sims 3 folder in Documents > Electronic Arts because you haven't been able to launch the game yet. It's not the cause of the unknown error but a result.
One of the causes of the unknown error is that the graphics card or chip's device ID isn't in the game's database, but it's easy enough to add yourself. Open Applications > The Sims 3, right-click on the Sims 3 icon itself, select Show Package Contents, and open this file path:
Contents > Resources > transgaming > c_drive > Program Files > Electronic Arts > The Sims 3 > Game > Bin
Inside the Bin folder, open graphicscards.sgr and cmd-F to search for Havendale , which will take you here:
vendor "Intel" 0x8086
card 0x0042 "Havendale"
card 0x0046 "Havendale"
Change the bolded 0042 to 87C0 , which is your graphics chip's device ID, but don't change anything else. If you accidentally delete something, quit without saving—I've seen something as subtle as an incorrect type of quote mark bork the edits. The lines should now look like this, other than the indents that this site isn't saving:
vendor "Intel" 0x8086
card 0x87C0 "Havendale"
card 0x0046 "Havendale"
This tells the game that your GPU is actually something else, but that's fine, it doesn't really matter how Sims 3 identifies the chip, only that it does so. After making this edit, try again to play with no packs installed.
If this doesn't work, and there were times when it did not for some players back when all we had was 32-bit, then I'd say it would probably be better to fix the 64-bit issue and install that version. And on that note, I would highly suggest contacting EA through live chat, or Twitter or Facebook, rather than sending an email. The email responses tend to be slow and utterly inadequate, at least from what players have reported here.
