My Sims 4 Legacy Edition game wont open through origin or the desktop

@queenrose68  I'm sorry, I really have no idea why the game won't run for you.  I've asked other people for ideas, and so far no one else has offered anything either.  I'll keep looking; I'm just saying I'm not sure what else to suggest.

One thing I am curious about though is what runtimes you have installed.  Hit Windows key-R and enter "appwiz.cpl" without quotes.  You'll get a list of installed programs, which you can sort alphabetically (if they're not arleady) by clicking on the Name header.  Please scroll down to the Microsoft Visual C++ Redistributables and take a screenshot of the entire list of these redistributables, so I can take a look at the years listed.

Then click "Turn Windows features on or off" in the upper left corner, and you should see something like this:

(This screenshot is from Windows 10, so it might not be exactly the same.)  Please take a screenshot of the .NET Frameworks, which should be at the top.

I don't know whether this has anything to do with your error, but it's worth checking, since a missing runtime would prevent the game from loading.

@queenrose68  The game should still open though, and I wish I knew why it didn't.  It seems that you don't have .NET Framework 4.8 installed, which is the current version.  From what I understand, it hasn't been necessary for Sims 4, but perhaps that's changed.

The framework is compatible with Windows 7, including 32-bit, so you can try installing it:

You just need the runtime, not the developer pack.

If you get an error that it's already installed, let me know.  It might be listed differently in Windows 7 (i.e. not right below .NET 3.5) for some reason.

@queenrose68  Thanks for letting me know.  I'm not sure what else to suggest, but someone else thought it might be worth doing a clean uninstall of Origin.  I know you did a regular uninstall before, but this process is much more thorough:

• First, clear Origin's cache (again; restart your computer if you get an error when deleting a file).
• 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.
• Download Revo Uninstaller (the free version is fine) from here.
• Launch Revo, select Origin from the list, and click Uninstall.
• When it finishes uninstalling, select "Moderate" under "scanning modes," and click 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 Sims 4 and 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."

@queenrose68  I'm sorry to say it, but I really don't know what else to do.  I've asked around, and I'll keep looking for more suggestions; if I hear anything, I'll post back and tag you.

I really wish I could help you with this.

I am having the exact same problem

I will wait if there's a solution because I really want to play Sims

@koniiGR  Are you specifically seeing the ntdll.dll errors when trying to play Sims 4?  If you're not sure, please post a dxdiag and check the Reliability Monitor, as described earlier in this thread:
