Hi yoshobanta garnaik,

I understand how confusing it is to not find .NET Framework 3.5 appears to be missing on your PC, even when you've already tried the standalone installer. In similar cases to this, the installation may be damaged or Windows may not have enabled the required components. Please try the following:

Press Win + S > search Turn Windows features on or off
Make sure .NET Framework (2.0 3.0...) entries appears
Open Command Prompt as Administrator.
Run: dism /online /enable-feature /featurename:netfx3 /all
After that, run: DISM /Online /Cleanup-Image /RestoreHealth
Finally, run: sfc /scannow > restart PC > test the application again.

If the DISM command fails or the issue still persists, it'd be helpful if you could give a few more details on the situation. It'd help us move on more suitable options, and avoid repeating what you've possibly tried:

Your exact Windows 11 Insider Preview build number (Settings > System > About).
Was there any error code shown during installation (e.g. 0x800F0950, 0x800F081F, 0x800F0922, etc.).

With that information, we can provide more specific troubleshooting steps.

Hi, that's actually normal. .NET 3.5 need to be downloaded (which you're trying to do). That's why I only asked you to check previous .NET versions if available. Could you please confirm your Windows 11 build by pressing Win + R > typing winver > press Enter?

Also, you mentioned missing. Here means you didn't see it in the Features, or that there's an error when you're trying to run an application? If you can share the message, that'd also be helpful.

Hi, from your screenshot, you're using the Single Language version. So just wondering, which 3.5 package did you download? If you installed the normal version, try the language version, and vice versa. Trying different installer might change the result: Install .NET Framework 3.5 on Windows 11 - .NET Framework | Microsoft Learn

Hi yoshobanta garnaik, sorry for the late reply, I was away.

Just to be sure, what exactly do you mean with "nothing happen"? What did you expect to happen after installing the .NET 3.5 standalone? Did the installer complete successfully, or do you receive an error? If it completes successfully, which application is still reporting that .NET Framework 3.5 is missing?

Because .NET 3.5 not appearing in Windows features is often normal for 26H1 version, what matter here is if the installer worked. If you're not sure, please open Command Prompt:

Run reg query "HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5"

If .NET Framework 3.5 is installed, you should get output similar to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5

Version REG_SZ 3.5.xxxxx

Install REG_DWORD 0x1
