What do you mean? I patched everything using the individual patches, not the launcher.

If there's something I need to know to patch properly, could you tell me please? Thanks.

Edit: After further research I realized that the game has the launcher error after 1.6.6 or later patches are installed. So how can this be rectified? I've done Google searches on this, and checked the BBS forums, to no avail. All the posts there talk about custom content, which hasn't been applied to the base game yet.

I think I'm finally starting to determine why this is happening. I just uninstalled Sims 3 and I was told that another expansion was installed, even though I had deleted and uninstalled every trace of expansion. I will try again, but that is probably the reason why I patched Sims 3 to 1.10 and still get errors.

If things continue to mess up like this I will just keep the patch at 1.7 and neglect updating any more. Any patch after that is just trouble so far.

There might be a big-patch thread so if this needs to be merged, I apologize.

I discovered this forum because I was googling my Sim 3 errors and I ended up here. I followed the advice stated in one of the threads to uninstall everything, and reinstall The Sims 3 step by step, patch by patch, without the assistance of the game launcher. And I did so. Around patch 1.8+ I noticed that the launcher said "There was an error during startup. Please see the Log for more details"

This is the same error I keep getting when I used the launcher to update from base game to 1.10. I don't know how to fix this error. I've uninstalled everything, followed exact instructions to delete all traces of Sims and EA from my system, and reinstalled. And everything appears to be fine until I install one of the patches.

None of my Sims 3 content, at this point, is arr'd. It's all original off the official DVD. I'm completely baffled and I have no clue why this isn't working. Because apparently I should be able to install every patch without problem. Nothing is modded, nothing is arr'd, it's just the original game. In addition I also took the liberty of uninstalling EADM too, which was supposedly responsible for some problems.

If I could find the logs I would gladly post them up here, but I have no idea where the logs might be.
