Need help with sims 3, it will not open (windows 11)

@Leliel2000  What happens when you try to open Sims 3, as in, where are you in the process when it fails and what do you see?  Please also let me know what kind of install this is: Origin, disc, Steam, or something else.

Your dxdiag only lists a large number of Windows update errors.  While these are unlikely to be directly related to Sims 3, it's a good idea to clean them up regardless.  Start with a couple of basic checks of your Windows system files:

• Hit Windows key-X
• Choose either “PowerShell (Administrator)” or “Windows Terminal (Administrator),” whichever option is offered
• Inside the window that appears, copy and paste “DISM.exe /Online /Cleanup-image /Restorehealth” without quotes, 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 “Windows Terminal (Administrator)”
• Inside the window, copy and paste “sfc /scannow” without quotes, and enter
• Post the message you receive here

Restart your computer, hit Windows key-i, select Update & Security, and click the box to check for updates.  If any install, restart again afterwards.

Once you've done all this, please try to open Sims 3 again, then look for new errors in the Reliability Monitor.  Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see a chart of errors and updates with a column for each day.

For any errors that mention Sims 3, or Origin if you use it, or any that happened at exactly the time you tried to launch the game, right-click on the error name and select "view technical details," then copy the info you see and paste it here.  I'm only interested in errors that happen after you run DISM and sfc.  If you don't see any, that's useful information too, but please check back at least an hour later in case the Reliability Monitor is slow to update.

Sorry for the late reply, when I try to open the the sims 3 some seconds go by before Origin shows back up again. When I have clicked the play button. 

I have follow you list down to the last detail and had no errors, when I write sfc /scannow it gives me the following message:

" Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection did not find any integrity violations."

I now just need to restart and do the rest. I will give a update when I have done the rest.

@Leliel2000  Please try uninstalling and reinstalling .NET Framework 3.5, which Sims 3 uses.  Hit Windows key-R and enter "appwiz.cpl" without quotes, and in the window that appears, click "Turn Windows features on or off."  .NET 3.5 should be at the top of the list; click the filled-in box next to its name to uninstall.  Restart your computer and repeat the process, except this time, click the now-empty box to reinstall, then restart your computer again.

So I unistalled .NET Framework 3.5 and I restarted my compute, but when I tried to reinstalle it, it gives me the error code 0x80246008 and that it couldn't be completed. It also askes me to restart my computer which I have done and then tried again but that didn't work. I don't know what to do anymore

@Leliel2000  It's possible that a third-party antivirus could cause this issue, so if you have one, try disabling it while you reinstall .NET 3.5.  As long as you don't open anything else while the antivirus is disabled, your computer should be safe.

If this doesn't help, or you don't use a third-party program, let me know.

I don't have any third-party antivirus that would stop it

@Leliel2000  Please open Windows Settings, then select System > Troubleshoot > Other Troubleshooters.  Click "Most frequent," then choose Windows Update > Run.  Let me know if you get any errors; otherwise, restart your computer and try to reinstall .NET 3.5 again.

If that doesn't help, please try a repair install:

You don't need a USB stick or DVD; you can just create an ISO, as described in the link in that guide.  This process preserves your personal data, but if you get to step 14 and are NOT asked what files you want to keep, back out and start over.

@puzzlezaddictIt states that it has registered a problem and it wants me to fix it with WaaSMedicService and I know I don't have that in my regedit and some other info my windows 11 is a dual-boot. I don't know if it has something to do with that

@Leliel2000  WaasMedicService is a part of Windows, so it should definitely be present in some form.  Having a dual-boot setup doesn't change that—Windows is still installed as normal on this partition.  What do you mean that you don't have the service?  Regedit is the Registry Editor, an application used to manually edit the computer's registry, as in, it's exposing the registry to the user.
