Uuugh I can't tell if I'm allowed to double-post or not. Buut...

I completely reinstalled Sims 3, and tried the page directly to 1.6.6. It works pretty well until Game\Bin\TSLhost.dll.
Now let me tell you; right now I have three different TSLhost.dll files. One from the razor > reloaded, one is the original, and another from the crack.
I've tried all three but it still isn't working.

I keep restoring to the original, but that blasted Patch log Viewer is telling me the same thing.

I'm going to try once again, but help would (once again) be so, so helpful.

My Sims 3 is arr'd, and when I searched for that file, it wasn't there.

Instead, I went ahead and downloaded the reloaded to razor patch, replaced Game and GameData, and now everything is patching beautifully.

EDIT: ...Except when I'm trying to patch to 1.6.6.
Searching for more info on 1.6.6 and why it isn't working here.

Another edit: So I checked the MTS guide on patching. And I figured out which file was missing/corrupted/exploded: Game\Bin\code_version.txt
As well as GameData\content_version.txt

I don't have back-ups of these two, and I'm not sure how to find them. I still have the download, so if anyone is willing to help a grasshopper out here, I'd be very thankful.

Thanks Enelen.
As I suspected it didn't work, so I'm off to Google those files.

Yes, I'm a lurker. And yes, I'm hilariously late in patching my game.
Whoops.
Sorry if this has been brought up before, it's amazingly late and I'm too tired to go through 14 pages of topics. I'm lazy, I know.

Anyway, today I figured I might as well patch my game. Mind you, my game was rescued from chainsaw-wielding sharks. So I can't use the crappy launcher patch stuff, since I need to use my firewall to block the internet. Which I find boring - but hey, it's definitely better than the fuzz knocking at my door.
So I went on several sites to find patches, and since I'm still on 1.0.631 and I'm guessing 1.2.7 is the next patch, I downloaded the patch and tried to install it. I'm looking if there are any patches between 1.0.631 and 1.2.7, but I'm pretty sure there isn't any.

Unfortunately the patch wizard decides to spazz and not let me patch, letting me know that hey - you're missing a file! Time to shut down the entire patching process while you grit your teeth and shout obscenities at your computer.

I'm not really sure what file I'm missing - the patch process stops at 85% and then a pop-up with that devilish red x appears.
Any help would be amazing.

Also, I don't think there are any issues with actually running the game: it's just the patching that fails.

Thanks much if you help, MATY folks.
