Sims 3 won't open: Alder Lake (Intel 12th-gen) CPU

Sure!
Once you have it pasted into Notepad:
1. File -> Save As
2. In the File name, name it something like sims3script.ps1
The important part is that it ends with .ps1
3. Save it somewhere convenient, like your desktop
4. Go to the file and Right-Click on it. There should be an option called "Run with PowerShell"
This will run the script with PowerShell. Once you open The Sims 3, the script will close automatically. Hopefully that helps.

I'm happy it works for you! <3
@armorguy1234 wrote:@puzzlezaddict Hmmm, well I tried the PowerShell script thing and it didn't work or maybe just did it wrong. I also downloaded process lasso but I have no idea how to use it lol.
I did have some random error once where the script spit out a bunch of red text when I ran it (an error with changing CPU affinity), but it fixed itself when I restarted my computer. Other than that, it has never failed for me. So unless you're seeing red text when you run it, I don't know what the problem would be. 
Just to clarify, you should see a window pop up telling you to launch The Sims 3. Once you have that, you should be able to open the game, then window will close on its own.
I might be able to help if you can give me more details on what is happening.
If you really can't get it to work then here's what I did for Process Lasso. Please keep in mind that it will run in the background and modify CPU affinities as you set them, unless you go down to your taskbar and exit it, so don't forget about it!
1. In the main menu, Options -> CPU -> CPU Affinities
2. In the Process Match box, you put ts3.exe OR ts3w.exe
You'll need to find out which version you have. I believe ts3.exe is the Origin version and if you're not on Origin it's probably ts3w.exe
3. In the CPU affinity box, just put 1
4. Click "Add Rule"
5. Click "OK"
6. Launch Sims 3 from the Sim 3 Launcher, it should open now. The game will run really slowly, so you need to set your CPU affinity to default.
7. Go back to Process Lasso and back to the menu from step 1.
8. Select ts3.exe (or ts3w.exe) under where it says "Process match" and then click "Remove" to remove it.
9. Click "OK"
10. In the middle-left portion of the window, click on the "Active processes" tab.
11. Find TS3.exe or TS3W.exe
12. Right click -> CPU Affinity -> Current - > Select CPU Affinity
13. There should be one box checked. Uncheck it. Make sure ALL boxes are UNCHECKED
14. Click "Invert Selection"
15. Click "OK"
And that should do it. Hopefully I didn't forget anything. >_< You would have to do that every time you want to play the game. Not sure if there's a simpler way, but that's what I did before I made the script.
