    Completely missing Dot Net in Windows 10 -1909?

    .NET Framework is built-into Windows 10 version 1903 and Windows 10 version 1909. It is not possible for at least this version of the .NET Framework to be installed.

    The error you have received, is likely due to the fact the application you are attempting to use, is specifically trying to target a version of the .NET Framework you don't have installed. I suggest using official Microsoft tool to download a Windows 10 version 1909 ISO. You can use the Media Creation Tool and/or the Upgrade Assistant. Windows ISO Downloader was only recently updated to support .NET Framework 4.8 on November 8th 2019. If you were not using Version 8.22, and would like to still use the tool, you need to download that version.

    RaymondCC .NET Detector looks at registry keys that are created when you install .NET Framework. It does not support the .NET Framework version that are included with Windows 8.0+

    The built-in version of the .NET Framework for Windows 10 version 1903 was .NET Framework 4.8

    .NET Framework 4.5+ has never been located in the list of Windows Features for any version of Windows. The lack of .NET Framework 3.5 is likely due to your WinSxS directory not containing it.

    You can install .NET Framework 3.5 if you run the same command you ran, but provide a source, to the components you need.

    This is due to the fact the .Net Framework 4.8 is already installed on Windows 10 version 1903 and Windows 10 version 1909. .NET Framework 4.8 is an in-place upgrade to .NET Framework 4.5

    This normally only happens when you have moved vital folders like the user's profile to a non-standard location.

    Your inability to install .NET Framework 3.5 is extremely easy to fix and likely the reason your unable to run the third-party application. Perform the following steps to solve that problem.

    1. Download a Windows 10 version 1909 ISO
    2. Mount the ISO within Windows 10
    3. Run the following command, the command assumes, the drive letter assigned to the virtual mount is D:
      • DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:\sources\sxs

    Source: Deploy .NET Framework 3.5 by using Deployment Image Servicing and Management (DISM)

    Hello,

    If you're referring to .NET Framework 3.5, try the DISM method to enable it on your system.

    Please refer following step-by-step guide:

    Completely missing Dot Net in Windows 10 -1909?

    I recently upgraded my Windows 10 Pro 1903 desktop to 1909. I downloaded the full 1909 ISO and run Setup.exe. The process went thru fine. However a program called 'Windows ISO Downloader' started giving Error 135. To my best understanding it occurs if required .Net framework is missing.

    I looked into Programs and Features and Turn Windows feature On/Off and there was no .Net framework in the list. There are 3 options called, .Net, .Net Extensibility 3.5 & 4.8 which just do not get enabled. I mean I can tick them but after Windows does something they go back to unticked state.

    There are no items like .Net 2 & 3.5 & .Net 4.8 under Programs.

    I tried to download any recent Windows 10 updates but it now gives error 0x80d02014 so it's altogether another issue. I do not know the state of .Net framework in 1903 as I never needed it ever in 1903, so this might have been a pre-existing issue or might have been introduced after 1909.

    Trying to install offline .Net 4.7 or 4.8 says that it's already installed as part of OS.

    I tried to download and run a third party utility that shows what .Net is present and it returns nothing. Below are relevant screenshots.

    Let me know if you have any further pointers for troubleshooting this issue. Clean install on Windows 10 might fix the issue but that's the last options. Looks like my current Windows 10 is in a total mess.

    Edit

    As suggested in comments I tried to use DISM to enable .Net feature but it returns Error 50. I ran CMD as admin. Unfortunately the contents of Log file are beyond my understanding.

    I tried to reset Windows 10 but to my surprise it says your apps shall be removed. Similarly Repair attempt tells me that no files and apps will be kept. The option to select first 2 of the 3 options is grayed out.

    I think there's something wrong with my Windows 10 1909 and I am still back to square one. I am sure clean install is going to fix it but it will be my last option.
