Sims 3 won't launch says unknown error oc

★★★ Newbie

Hi. I just reinstalled my games because it wouldn't let me install content but now it says unknown error occurred when I try to launch my game. This happens even though I only have the base game installed..

@Stinekiksk  It sounds like you previously had TS3 installed on this computer?  If so, the issue may be that the uninstaller didn't remove the game's hidden library files.  The presence of these files can throw an unknown error even when there's no other problem with your install.  It's best to start with a clean uninstall, removing all files before reinstalling.  Here's a guide on how to clear out the hidden library files:

Once you've reinstalled the base game, run the Super Patch (digital download version) to manually patch the game to 1.67.  The launcher doesn't always do a thorough job of patching on its own.

If you still can't launch the patched base game after a clean uninstall, you may need to edit TS3's .sgr files to force recognition of your graphics card.  If you'd like help with this process, just ask, and please list your computer's specs, along with the device ID of your card.  Here's how to find that information:

Or, if you find your particular card on the list, you can add the proper text to the two files yourself.  Be sure to edit both graphicscards.sgr and graphicsrules.sgr.

 

If you can launch the patched base game, you can start adding your packs.  You may need to apply two more workarounds, depending on which packs you plan to install, but those are fairly straightforward.  Just let me know the packs you're using, and I'll write out the instructions.
