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.

I followed everything you told me to do, to a t. It still gives me the same error.

I've uploaded my DxDiag.txt, it is in the attachment.

@Avareee  Do you have any Adobe software running on your computer?  If so, try killing it through the Task Manager before trying to play.  Your dxdiag lists crashes from a service supposedly associated with Adobe, and while there's no way to tell from the dxdiag whether this is happening while you try to play, it's easy enough to test.

If that doesn't help, please run a couple of basic checks on your Windows system files:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Command prompt (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes into the window, and enter
• The system will start validating soon. If it throws an error, please list it here
• After it reaches 100%, hit Windows key-X again
• Again, choose “PowerShell (Administrator)” or “Command prompt (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes into the window, and enter
• Post the message you receive here

Restart your computer, then try playing again.  If that doesn't help either, try playing in a clean boot:

https://www.windowscentral.com/how-clean-boot-windows-10

When you reboot, go through the Task Manager's background processes list shutting down anything that doesn't absolutely need to be running—some services don't get disabled even in a clean boot.  Disable your antivirus as well, at least long enough to test.

So, first...

I couldn't find any program called Adobe on my computer and/or in the Task-Manager, though I found "Adobe Flash Player"(not in task-manager but installed programs), deleted it and restarted my PC, tried starting The Sims 3. -- problem persisted.

Then I did the Command Prompt things you told me to do, these were the results: (attachments)

The problem persisted.

I tried the clean boot, via msconfig (your link), I've just had to disable, my Antivirus(no other programs other than the Nvidia driver-panel which I have disabled aswell) and in the task-manager all were already disabled, as I have done something similar to this before. 

So I (clean) booted the PC, but my Antivirus(Kaspersky) was still being launched even tho I had disabled that in msconfig, I checked the task-manager as you told me, I tried to end the task it didn't work, so I have ended Kaspersky, just in the taskbar below(where all the background programs usually are). But didn't find any other programs(in the task-manager) which I would find conflicting with the launch of Sims3.

So I've gone ahead and started Origin(as admin), and tried to launch Sims3, but the problem persisted. Still.

@Avareee  Please uninstall your VC++ runtimes again, then download the "All in One Runtimes" and DX9 from here:

https://www.sereby.org/site/All%20in%20One%20Runtimes&lang=en

(Click the Download header to see the actual download page; you don't need to donate anything to download.)  Restart afterwards.

If that doesn't help either, please run a dxdiag and attach it to a post.

https://help.ea.com/en/help/pc/how-to-gather-dxdiag-information/

For a moment I thought it is going to work... but no :/

Still the same error code.

DxDiag.txt is in the attachment.

EDIT: Would you consider this program to be safe? 

https://www.majorgeeks.com/files/details/tweaking_com_windows_repair.html

(source)

If so, I'm planning on trying to fix the issue by doing this 'routine':

use CC Cleaner
Restart PC
Run Windows Repair Free/Pro 
Restart PC
Delete all Runtimes C++ and 'deactivate' .NET Framework.
Restart PC
use CC Cleaner
Restart PC
Run the Runtimes C++ AIO, reactivate/install .NET Framework and DirectX 2010
Restart PC

And try to run The Sims 3.

@Avareee  Sorry for the late reply; I wanted to get a second opinion before posting more suggestions.  And no, I wouldn't use a tool like the one you linked.  I don't know for a fact that it's unsafe, but it may well be, and there are much more reliable ways to repair your system.

To start with, download Malwarebytes (the free version is fine):

https://www.malwarebytes.com/mwb-download

Open it, click Scan > Custom Scan > Configure Scan, check all the boxes both for scans and for your C drive (and any other if you happen to have an external plugged in), and let it do its job.  This will probably take at least an hour, so you may want to set it to run while you're doing something else.  Let me know what it finds.

If you want to make sure Windows itself is intact, a repair install is the best approach.  It only requires as much time as it takes to download a Windows 10 ISO and to reinstall Windows.  To be clear, I'm not saying you need to do this now, just that it's not too complicated if you want to.  Here's a good tutorial:

https://www.tenforums.com/tutorials/16397-repair-install-windows-10-place-upgrade.html

You'll be able to keep your existing user data and programs, but it's still a good idea to back up anything critical first.  If you do not see the option to keep personal files as shown in step 13, back out and try again.

If you don't want to run a repair install, at least check for Windows updates: hit Windows key-i, select Update & Security, and click the box to check for updates.  If anything installs, restart when it's done.

Either way, please uninstall Sims 3 and Origin as described before (using Revo).  However, when clearing Origin's cache, open the LocalContent folder and delete the Sims 3 folder inside, despite the article's instructions saying to leave that folder alone.  After uninstalling, feel free to do a pass with CCleaner, but you should only need to do the one; it can be counterproductive to keep letting it search for more files to delete.

With Sims 3 and Origin uninstalled, deactivate .NET Framework 3.5: hit Windows key-R, enter appwiz.cpl, click "Turn Windows features on or off," uncheck the box next to .NET 3.5, and restart once it's uninstalled.  Then repeat the process to reinstall .NET 3.5.  Even if you've done this before, please do it again after all of the above.

Reinstall Origin using the full installer linked before, and run it as an admin from now on.  Install Sims 3 on your internal drive and run it as an admin as well, which you can do from its shortcut or from TS3.exe within the game's program files.

Yeah, no problem about the late reply.

I did a 'full scan' with the program you've suggested(Malwarebytes)

And it really did find some threats. (The report is in the attachments)

And I did everything you told me to do again, in the same way.(except windows repair)

Windows Update

Restart

Uninstall Sims 3 + Origin via Revo.

Ran CCleaner once

Restart

Deactivated .NET Framework 3.5

Restart

Activated .NET Framework 3.5

Restart

Installed & Launched Origin + Sims 3(TS3.exe) Via Admin.

And it still gave me the same error. (0xc000007b) ☹️

EDIT: 

By the way I did a registry scan via CCleaner, didn't clean it though.

It showed me this(and other rather non important things, which I purposely didn't cap on the screenshot):

https://i.imgur.com/pQkyZxH.png

which I thought may is the cause of the error, or are those files of older versions, which aren't needed anymore?

What do you think?

@Avareee  The .NET version listed in your screenshots is 1.0, which Sims 3 doesn't use, so I don't think it's relevant.  Besides, if .NET were the issue, uninstalling and reinstalling it should have restored any missing or corrupt files.

I asked for a second opinion (again) about the Malwarebytes report, and this person, who knows a lot more about Windows than I do, thinks that the best way to clean up the system is to do a fresh install of Windows, as in, wipe the hard drive completely.  I understand why you might not want to, but given the various malware elements listed, it's at least worth considering.  In particular, Searchscopes is difficult to get rid of, and given the list of other PUPs, there may be more lurking on your PC.

One thing worth noting:  You may have installed Restoro yourself, but this is what Malwarebytes has to say about it:

https://blog.malwarebytes.com/detections/pup-optional-restoro/

Programs like this that claim to clean or restore Windows are totally unnecessary—a repair install is more efficient and far mor trustworthy—and usually do more harm than good.

Again, if you don't want to do a fresh Windows install, I understand, but I'm otherwise out of ideas here.  This error hasn't responded to any of the usual interventions, unfortunately.  Just to be clear though, I can't say for sure that even a clean Windows install would make Sims 3 work, since I don't know why it currently doesn't.

Hello again, hmm yeah that's probably going to be it. A Clean install of Windows.

Though I had a weird thing today, I deinstalled Origin and Sims3 with Revo Uninstaller.

And installed the game through my old TheSims3 disc which I have found laying around at home. And guess what, it worked... and stopped giving me the error-code.

But I was forced to download Origin to have access to all the addon packs/dlcs.

So, I have installed Origin. Even if the game was installed under ProgramFiles(x86)/Electronic Arts, Origin was able to find the TheSims3 folder, which was suprising to me.

But as soon as I launched Origin, it wanted to update the game.

And after the update it stopped working again, giving me the same old error-code. Seems like it downloads something and breaks the game for me.

Wanted to update you on that, maybe you'd know better, and would be able to help me.

Other than that, I wanted to thank you that you tried to help me fix my game.

EDIT:

And about the 'Restoro' program, I may have downloaded that one, but never used it. I don't even remember why I have installed it, if it was me (or a virus?) downloading it.
