Still if it does not settle the matter, it will be compulsory for you to uninstall the game. You still have the possibility to restore your system back to a restore point before the updates. If however, you see that you cannot run the file, then you will be compelled to get the game removed and installed back. I update this page as I add mods to my game or remove the ones I no longer use. Just like my Sims 2 mods list and Sims 4 mods list, this list is a constant work in progress.
These are all the mods I use in my game, organized by category. Here is my recommended mods list for The Sims 3. It will directly run the game without making use of the launcher that is causing so much trouble to you. Little Mortimer scours the web for all the best Sims 3 Mods. Now that you have reached the TS3.exe file, simply run it. In the situation that you do not find the Electronics Art folder there, please consider carrying a search over your system for reaching it out. The default install path for the game is C:\Program Files\Electronic Arts\The Sims3\Game\Bin from where you will find a file TS3.exe. You should try it to see whether you get playing the game then. You can easily run the game without the use of the launcher, it is perfectly possible.
You should be thinking of getting the Registry entries corrected by repairing your system with your installation cd but there is far more simpler way than that to get the matter settled down. There are many who start having problems with the launcher while registry entries are corrupted. There are many people who complain about having problems with the launcher as you should have noticed in the Kioskea forum.
