@ddgraham This is usually a system issue: .NET Framework 3.5 should install fine on even a fully-updated Windows. So please run 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.
Try installing .NET 3.5 again, and if that doesn't work, try a repair install:

This shouldn't erase any of your data, but if you get to step 14 and are NOT asked whether you want to keep your apps and files, back out and start over.

@Mikey009556 Use Option Two in the guide rather than Option One.
If that doesn't help, please run a dxdiag and attach it to a post. Please also let me know exactly what error you're seeing, if any, when trying to open Sims 3.

yeah none of the options above worked. so i bought the sims 3 for the first time and whenever i try to launch it, a pop up appears saying i have to download net framework 3.5, so when i try to download it i get an error message.

@Mikey009556 I do think you need to run a repair install, but your C drive doesn't have enough space to download a Windows 11 ISO. Please clear another 20 GB or so, in whatever way works for you. Your D drive has plenty of free space, so it shouldn't be too difficult.
If option two for the repair install still doesn't work, please let me know exactly how it doesn't work: what step you're on, any error message you get, etc. I've seen this exact .NET error before, and the repair install was the only fix short of reinstalling Windows, which I'm sure you don't want to do.
