Re: Bought Sims 3 but the game won't launch (0xc00007b) !
@Avareee Since you've messed with the game's program files, please do a clean uninstall and reinstall of both Sims 3 and Origin. It's not necessary to mess with TS3.exe or any other game files, but the changes you've made could prevent the game from working now even after you've addressed the original issue.
Start by uninstalling Sims 3:
- Download Revo Uninstaller (the free version is fine) from here.
- Launch Revo, select Sims 3 from the list, and click Uninstall.
- Once the game is uninstalled, select "Moderate" under "scanning modes," and click Scan.
- Review the list, in case there's something you want to save; otherwise, click Select All, and then Delete.
- Close Revo, and restart your computer.
Next, uninstall Origin:
- First, clear Origin's cache.
- Quit Origin, then right-click on the Task Bar and open the Task Manager. Scroll through looking for Origin entries. If you find any, click on them and End Task.
- Launch Revo again and uninstall Origin, and when it's uninstalled, select "Moderate" again and Scan.
- If Revo finds any remaining registry entries, select all, delete, and click Next.
- Revo will display "Remaining Data and Folders. Select all of them except for the "Origin Games" folder, if it appears. (This is where other Origin games are installed by default.) Delete the rest.
- Close Revo, and restart your computer.
Next, download the full Origin installer and run it. Here's the direct download link:
http://download.dm.origin.com/origin/live/OriginSetup.exe
Be sure to run both the installer and Origin itself as an admin: right-click on each and select "Run as Administrator." When it's reinstalled, download Sims 3; you can just download the base game, to save time, if you want.
If you get the same error, please try reinstalling DirectX 9. You don't need to uninstall anything; just download the installer from Microsoft and run it.

By the way, Sims 3 specifically uses VC++ 2005 x86 and .NET Framework 3.5, so if you didn't address those specifically, please do so now. It sounds like you don't need instructions, but for .NET at least, please uninstall it through the "turn Windows features on or off" list, restart your computer, reinstall .NET, and restart again.
If none of that helps, please run a dxdiag and attach it to a post.
