Windows 10: Need to install .net version 3.5 offline

Hello,I need to install .net version 3.5 offline. My first computer is windows 10 and my second is windows 11 version 23h2. I need to install .net 3.5 onto the windows 11 version 23h2. My windows 10 computer has internet, so I am trying to do this using a USB stick. The problem is that I can not find a microsoft page with .net for windows version 23h2.

Unable to download any framework for .net - (error code 0x80070002)

OK, the Windows 10 Feature installation method should have been straightforward, but since that errored out as well, something else seems to be going on with your Windows, so wait for somebody with more experience to suggest a way out.

In the mean time, if you haven't already, you could give muchomurka's suggestion a go as well with the elevated prompt and an install media to see if it works. The following link shows the detailed steps involved.

Were these steps you followed to download the .NET Framework 3.5 offline?

If you did, here is the second part to install it:

You might want to try copying everything off the thumb drive to a local folder on the hard disk instead of running setup from the thumb drive itself.

 

Installing .NET 3.5 offline

I searched on the web and I am trying to follow guides on how to install .NET 3.5 on an offline machine. Steps that I followed:

1. Download official Windows 10 .iso
   
2. Mount it on D: drive
   File explorer which shows mounted Windows 10
   
3. Run dism /online /enable-feature /featurename:NetFx3 /All /Source:\sources\sxs /LimitAccess
   
4. What I get back:
   

Error: 0x800f081f The source files could not be found. Use the "Source" option to specify the location of the files that are required to restore the feature.

I cannot solve this error, can someone help me out? I thought that feature naming might be bad, I opened mounted Windows .iso and navigated to D:\sources\sxs where I was able to find 4 files:
